A vapor-deposited layer may be provided by vapor-depositing aluminum, a shell, or the like on the surface. Also,
In the above embodiment, there are irregularities 2 on the outer surface of the synthetic resin molded product 1.
However, instead of this, the unevenness 2 may be formed on the inner surface of the molded product 1. Further, the shape of the molded product 1 is not limited to a cylindrical shape with a bottom, but may be a bowl shape, a spherical surface, or other shapes.

なし得る。<Effects of the Invention> According to the present invention, by installing the sheet 3 printed with the ink 4 having high hardness into the cavity 6 of the molding die 5, the synthetic resin is Since the ink 4 can form the unevenness 2 on the surface of the molded product 1, there is no need to carve fine unevenness in the mold 5 to form the unevenness 2 of the synthetic resin molded product 1, and the sheet 3 can be simply Synthetic resin molded product 1 with the same mold 5 by changing
It is possible to form many types of unevenness 2 to form satin patterns, lattice patterns, letters, figures, etc. on the surface of the mold.Therefore, the number of molds 1 can be minimized, and the shape of the mold 1 is very simple. The mold 1 can also be manufactured easily and inexpensively.

でき、その実用的効果は著大である。 In addition, after the synthetic resin molded product 1 is molded so that the sheet 3 is polymerized on its surface, the synthetic resin molded product 1 is taken out from the mold 5 with the sheet 3 remaining in the mold 5. The synthetic resin molded product 1 of the same shape can be repeatedly molded by using it many times, and the sheet 3 is not wasted, which is economical, and the trouble of attaching the sheet 3 to the mold 5 can be saved. The molding operation is also simplified, and therefore, the synthetic resin molded product 1 can be produced easily and inexpensively, and the synthetic resin molded product 1 having exactly the same shape can be molded reliably and easily. Moreover, since the sheet 3 is formed into the surface shape of the synthetic resin molded product 1 by vacuum forming so as to have a shape that matches the inner surface of the mold 5 of the synthetic resin molded product 1, the sheet 3 is formed into the molding die 5 of the synthetic resin molded product 1. When installing in the cavity 6 of 5 or synthetic resin molded product 1
When molding, the sheet 3 can be brought into close contact with the inner surface of the molding die 5. Therefore, when taking out the synthetic resin molded product 1 from the molding die 5, the sheet 3 can be securely left in the mold 5. It can be easily taken out in the same state, and its practical effects are significant.
