PROBLEM TO BE SOLVED: To ensure resin strength by eliminating remaining of a weld inside a resin when a resin case having a hole, a recess part and an insert member is manufactured. SOLUTION: When the resin case having the hole 3 and the insert member 4 is formed by using a metallic mold, a molten resin is charged into the metallic mold at first. Further after charging the resin into the metallic mold, a pin 30 and the insert member 4 for forming the hole 3 are pushed into the molten resin 2a in the metallic mold just before completion of charging the resin into the metallic mold.
