PROBLEM TO BE SOLVED: To provide a composite molding with a high productivity that has a high adhesion strength and reduced deterioration of quality including the roughness on the surface of a primary molding and a dimensional change.SOLUTION: The composite molding 1 according to the invention comprises a crystalline resin molding 10 having a low-crystallized surface 10a where a part of the crystalline resin molding is low-crystallized; and the other molding 20 adjacent to the molding 10 at the low-crystallized surface 10a. The composite molding 1 is produced by low-crystallizing a part of the crystalline resin molding 10, placing an uncured material on the low-crystallized surface 10a, applying a stress onto the low-crystallized surface 10a, and curing the uncured material. The uncured material is preferably provided by introducing the crystalline resin molding into an injection molding die so that the low-crystallized surface 10a is visible, and injecting and pressing the uncured material to place it on the low-crystallized surface. The low-crystallization of a part of the crystalline resin molding is preferably carried out by laser irradiation. |
