PROBLEM TO BE SOLVED: To provide a manufacturing method of a composite molding composed of a metal molding and a resin molding.SOLUTION: A manufacturing method of a composite molding includes a step for laser scanning so that markings 5 composed of each straight line and/or each curved line do not cross each other when forming the markings 5 composed of the straight line and/or the curved line in the single or different direction on a joint face 1a of a metal molding 1, and a step for disposing a part including the joint face 1a of the metal molding 1 on which the markings 5 are formed in a mold, inserting a resin, which is a precursor of a resin molding 2, and jointing the metal molding 1 and the resin molding 2 without using a binder. In the step for laser scanning, the marking pattern composed of a combination of a plurality of kinked lines protruding to the same direction is formed on the joint face 1a of the metal molding 1.SELECTED DRAWING: Figure 1 |
