Beschreibung
Zusammenfassung:	A manufacturing method of a resin molded article (5, 313, 353), includes a primary molding step of molding a primary compact (3, 321) having an optical element (1, 312, 52) and a protruding portion (2, 320) that protrudes from the optical element (1, 312, 52) by using a light transmissive molding material, and a secondary molding step of molding a secondary compact (4, 306a, 316, 351) that supports the primary compact (3, 321) by using a molding material different from the molding material of the primary compact (3, 321) and integrating the primary compact (3, 321) with the secondary compact (4, 306a, 316, 351), wherein the protruding portion (2, 320) is molded to protrude on the secondary compact (4, 306a, 316, 351) side, and at the primary molding step, the molding material of the primary compact (3, 321) is supplied into a molding space (1A) for the optical element (1, 312, 52) from a gate (24a, 322a) of a molding die (29) for the primary compact (3, 321) through a molding space (2A) for the protruding portion (2, 320) and it is thereby supplied into a cavity (34) of a molding die (29) for the primary compact (3, 321).
