A molten material is filled into a molding space defined between the metal molds, and thereby a molded article having a shape corresponding to the housing is molded. The molded article has a plurality of first pin-receiving portions serving as the bosses, and a plurality of second pin-receiving portions projecting from the second walls. The first and the second pin-receiving portions are pushed by a plurality of ejector pins, and thereby the molded article is ejected from the metal molds.
