Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an in-mold molding method by which the molding of a resin molded product and painting on the surface are simultaneously carried out, a partition line formed on the surface of the resin molded product is controlled to only one or zero and the wrinkle produced on the surface of the finished resin molded product is minimized to finely decorate the surface.SOLUTION: A transfer sheet (10) is sucked on a cavity molding surface (32) by arranging the cylindrically rounded transfer sheet (10) in the mold (34) forming a cavity (42) having an opening (45) and evacuating a portion between the transfer sheet 10 and the cavity molding surface 32 through a suction passage (44) and after that, the opening (45) is closed with a core mold (38) to seal the cavity (42) and the molten resin (Y) is injected into the transfer sheet (10).
