To secure effects for preventing hurting, fouling, etc., without changing a protective sheet stuck to a pattern sheet with an uneven pattern in a whole process from the processing to the molding completion of the pattern sheet and to form the distinct uneven pattern with regard to a plastic molding forming an uneven pattern corresponding to a pattern in the pattern part of the molding during pattern transfer injection molding or pattern sheet insert injection molding.

A pattern surface is formed on the molding by the pattern sheet. In order to form an uneven pattern corresponding to the pattern surface, on the protective sheet 15 stuck to the surface of a substrate sheet 11 for the pattern sheet, the uneven pattern 16 corresponding to the pattern is cured/formed by printing using an ultraviolet curable ink etc.
