PROBLEM TO BE SOLVED: To provide a method of producing a composite molded body, by which adhesive strength in differing directions can be increased and processing speed can be increased.SOLUTION: A method of producing a composite molded body in which a metal molded body and a resin molded body are bonded together includes: a step in which a continuous laser beam is used to continuously irradiate an adhesion surface of the metal molded body with a laser beam at an irradiation speed of 2,000 mm/sec or more; and a step in which a molded-body section that includes the adhesion surface irradiated by the laser beam in the previous step is positioned in a mold, and a resin that becomes the resin molded body is subjected to extrusion molding, or a step in which the section, which includes the adhesion surface irradiated with the laser beam in the previous step, and the resin that becomes the resin molded body are pressure molded in a contacted state. |
