<P>PROBLEM TO BE SOLVED: To provide a resin molding and a method of manufacturing the same by which when a multi-layered resin molding product is molded by casting molding, the product is molded using a mold having simplified structure and troublesome work can be omitted. <P>SOLUTION: The resin molding includes a first resin molding layer 1 and a second resin molding layer 2 molded by the cast molding. The first resin molding layer 1 has a groove mark 16 for air vent being the mark of the groove 13 for air vent for extracting air in a cavity 38 when casting the second resin composition into the cavity 38. The groove mark 16 for air vent is positioned in a boundary between the first resin molding layer 1 and the second resin molding layer and exposed on the end face 86 of the molding comprising the first resin molding layer 1 and the second resin molding layer 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
