Abstract
There is provided a method of manufacturing a composite molded body that can increase a processing speed and a joining strength in a different direction. The method of manufacturing a composite molded body in which a metal molded body and a resin molded body are joined, includes the steps of: continuously irradiating a joint surface of the metal molded body with laser light at an irradiation speed of 2,000 mm/sec or more by using a continuous-wave laser; and arranging, within a mold, a portion of the metal molded body including the joint surface irradiated with the laser light in the preceding step and performing injection molding of a resin forming the resin molded body, or performing compression molding in a state where a portion of the metal molded body including the joint surface irradiated with the laser light in the preceding step and a resin forming the resin molded body are made to contact with each other.
