PURPOSE:To produce the insert molded product without the unnecessary hole of the mark of a holding pin which is a part of the insert surface exposed on the molded product by exchanging a top force, while forming the holder for supporting the insert by the top and bottom forces. CONSTITUTION:A top force 14 is caused to be in contact with a bottom force 15, and synthetic resin is poured. The top force 14 is lifted and a holder 16 is formed in the bottom force 15. Next, the bottom force is placed under another top force 17, and an insert 13 is fitted into a groove 16a, and at the fixed state thereof, after the top force 17 has been caused to be in contact with the bottom force, synthetic resin is poured into the mold cavity 18, thereby obtaining the synthetic resin-molded product containing the insert 13.
