PURPOSE:To prevent the damage and deformation of an insert part by molding a coating layer on the part coming into contact with a mold of the insert part to perform insert molding and subsequently removing the coating layer by dissolution, melting, sublimation or decomposition. CONSTITUTION:An adhesive layer 6 is formed on a first insert part 2 having a colored layer 5 formed thereon and a through-hole 7 is formed to a second insert part 3. A coating layer 21 is formed on the parts coming into contact with a mold of the insert parts 2, 3. The coating layer 21 is formed by applying an aqueous solution of a water-soluble polymeric substance such as starch to the insert parts 2, 3 to dry the same. The coating layer 21 is formed up to the peripheral edge part of a resin part 4 so as to slightly exceed the edge parts of force-cutting parts 16, 17, 18. Subsequently, the peripheral edge part of the insert part 2 and the insert part 3 are pushed in the cavity of the mold 10 to be clamped. The part 2 is held between the force-cutting parts 16, 17 and the part 3 is pressed to the force-cutting part 18 by a pin to be positioned but the damage and deformation of the parts 2, 3 are prevented by the coating layer 21. |
