Description of the Related Art Generally, an absorbent article such as a disposable diaper wraps an absorbent for absorbing and retaining bodily fluids with a facing material disposed inside the absorbent article and a surface sheet disposed outside. It has a structure that includes it. The sheet material of this absorbent article has water impermeability so that the liquid absorbed by the absorbent material disposed inside does not seep outside, and water vapor and the like generated inside stay inside the absorbent article. In order to prevent the occurrence of stuffiness, it is also required that the water vapor has a suitable degree of moisture permeability for transmitting and radiating water vapor to the outside.

Adhesion with other members and molding to a required shape are performed. Thus, the constituent fibers of the nonwoven fabric formed by heat fusion are required to have heat fusion properties. Conventionally, various fibers have been put to practical use and have been proposed as the heat-fusible fiber. For example, fibers made of polypropylene, ethylene-based polymer, polyester, and the like are known. Japanese Patent Publication No. 55-26203 discloses a resin comprising a polypropylene-based crystalline copolymer composed of propylene, butene-1 and ethylene, and a non-crystalline ethylene-propylene random copolymer,
Or, a polypropylene heat-fusible fiber containing the resin as at least one component has been proposed. Further, Japanese Patent Application Laid-Open No. Sho 62-156310 proposes a polypropylene-based adhesive fiber mainly composed of a raw resin obtained by mixing an ethylene-propylene random copolymer alone or a mixture of the copolymer and crystalline polypropylene. .

In addition, the nonwoven fabric used for the sheet material of the absorbent article such as a disposable diaper has a good tactile sensation without giving a so-called stiff and hard feel in response to the movement and the shape change of the absorbent article during use.
