ABSTRACT:
A resin molded article (1) is formed such that a primary molded article (10), collars (40) and a metal flat plate (50) are molded integrally as inserts in a secondary molded portion (30). A rib (12) extends in a longitudinal direction along a surface of the primary molded article (10) that is adjacent to a surface facing a gate (62), but not a terminal surface (13). Supports (61) are provided intermittently along the longitudinal direction on a cavity inner surface (63) of a molding die (60) for supporting the rib (12). The primary molded article (10) is reinforced by the rib (12), and is not likely to be deformed by resin injected from the gate (62) and is not likely to be displaced.
