ABSTRACT:
A method of eliminating difficulties in holding inserts at the time of molding, and for ensuring the inserts at predetermined positions is provided. According to this method, the edges of the inserts are alternately arranged in a stair-like state. These edges are held by a stair-like holding portion formed by an upper metal mold and a slide metal mold, and/or a lower metal mold and another slide metal mold, so that they can be secured at predetermined positions. Thereafter, resin is injected into the cavity formed inside the metal molds.
