Description of the Related Art Generally, a wearer has a body fluid-permeable top sheet, a body fluid-impermeable and vapor-permeable backsheet, and an absorber interposed between these two sheets. 2. Description of the Related Art A deployed disposable diaper is well known in which both side edges of a dorsal portion located on the back side of a wearer are fastened to an abdominal portion located on the abdominal side of a wearer and worn. In this disposable diaper, adhesive tapes and mechanical fasteners are provided on the left and right side edges of the back side, and a fastening portion where these adhesive tapes and mechanical fasteners are detachably fastened is formed on the abdominal side. It is worn with an adhesive tape or a mechanical fastener fastened to the fastening portion. As such a back sheet of a disposable diaper, from the viewpoint of body fluid impermeability, vapor permeability, workability, and the like, microporous materials produced by adding a filler as a microporous inducing agent to a thermoplastic resin and stretching the same. Quality film is used.

There is provided a see-through portion 11a in which 1b is formed. The transparent portion 11b is formed by embossing substantially the entire transparent portion 11a. The see-through portion 11a
Is required to be provided at a substantially central portion in the length direction of the back sheet 11 over about one third in the length direction. This is because the colored portion of the absorber colored by the excrement is located inside this portion (on the skin contact surface side) and is observed through this portion. The total area of the transparent portion 11b is:
It is necessary that the area be 5 to 70% of the area of the back sheet 11. If it is less than 5%, it is difficult to confirm coloring of the absorber through the transparent portion 11b, and if it is more than 70%, a large number of fine holes formed in the back sheet 11 are crushed, so that proper vapor permeability of the back sheet 11 cannot be secured.

１１ｂが複数形成されている。More specifically, the back sheet 11 is made of a thermoplastic resin such as a crystalline polypropylene resin, which is miscible with the thermoplastic resin while the thermoplastic resin is being melted. At a temperature below the crystallization temperature, a compound that undergoes phase separation is melt-blended, a sheet is formed, phase separation is caused in the cooling process, and the sheet is stretched to obtain an interface between the thermoplastic resin and the compound that have undergone phase separation. It is formed using a microporous sheet produced by causing peeling as a material sheet. Even if such a microporous sheet is manufactured using a transparent material, it is substantially opaque due to light scattering in its internal structure. The transparent portion 11a is embossed on substantially the entire transparent portion 11a by pressing an embossing roll having a linear embossed convex portion. Then, as shown in FIG. 2, the fine holes in the portions pressed by the embossed protrusions are not crushed by the embossing process, so that light scattering is eliminated, and a band-shaped transparent portion (band-shaped portion) is formed.
11b are formed in plurality.

It can also be formed by applying a wax, a varnish, a hot melt agent or the like. Examples of the wax include paraffin, microcrystalline, polyethylene, polypropylene, beeswax, montan, anhydrous lanolin, carnova, and the like. Examples of the varnish include those containing resins such as polyamide, acrylic polymer, vinyl polymer, urethane, chlorinated polyolefin, and rosin.

More preferably, 50 to 50 are formed. The transparent portion (band portion) 11b may be transparent or translucent, and preferably has a whiteness of 60 or less. This is because if the whiteness exceeds 60, it is difficult to confirm urine from the outside of the sheet. The whiteness was measured by placing a black plate on the back of the sheet and measuring the whiteness with a spectral color difference meter SZ-80 manufactured by Nippon Denshoku Industries.

In the disposable diaper of the present invention, since the transparent portion is formed by embossing, it is possible to form the transparent portion by using the conventional embossing for securing flexibility and avoiding noise, thereby enabling efficient production. It is. As a material sheet for forming the back sheet 11, as described above, the thermoplastic resin is miscible with the thermoplastic resin while the thermoplastic resin is being melted, and is not more than the crystallization temperature of the thermoplastic resin. In addition to a microporous sheet in which the compound to be separated is melt-blended and stretched to form micropores, a thermoplastic resin such as polyethylene is mixed with a filler such as calcium carbonate as a micropore-inducing agent to stretch the micropores. A microporous sheet formed with, or a thermoplastic resin such as crystalline polypropylene was cold-stretched, a void structure was formed by material destruction, and the pores were hot-stretched until a continuous structure was formed to form micropores. A microporous sheet or a microporous sheet obtained by mixing a filler soluble in a thermoplastic resin and dissolving the filler to form micropores can also be used.
