INSERT MOLDING COMPONENT AND MANUFACTURING METHOD OF INSERT MOLDING COMPONENT

Problem The present invention aims to facilitate the quality control while forming an opening which partly exposes a surface of the base member on a covered member, in an integrally form insert molding component which is integrally molding a covered member on a plate-like base member and the manufacturing method. Means for Solving the Problem A plate-like base member (26) and a covered member (31) integrally formed with the base member (26) are equipped. An opening (32b) exposing a surface (26m1) of the base member (26) is formed on an one side of the base member (26) of the covered member (31) in the plane perpendicular direction, and a molding time supporting portion (36) supporting a reverse surface (26m2) of the base member (26) at the time of insert molding is provided on the other side of the covered member (31) in the plane perpendicular direction, where is a reverse side of the opening (32b).
