Flow gates 5 capable of protruding and retracting are provided in a cavity 9 of a die 2 to control a resin filling path. The generation of welds or orientation lines in a resin flow pattern is allowed only in an area containing uneven portions outside a design surface but is not allowed in other areas. The area containing welds or orientation lines in a resin flow pattern is covered with a separate component having a design surface, thereby achieving a desired metallic appearance.
