Abstract
A method for roughening a surface of a metal molded body which can be used as an intermediate for manufacturing a composite molded body of a metal molded body with a resin, a rubber, a metal, or the like is provided. The method for roughening a metal molded body surface includes a step of irradiating the surface of the metal molded body with laser light at an irradiation rate of 2000 mm/sec or more with an energy density of 1 MW/cm2 or more using a laser apparatus, and the laser light irradiation step is a step of irradiating laser light so that laser light-irradiated portions and non-laser light-irradiated portions are generated alternately when the laser light is irradiated to be in a straight line, a curved line, or a combination of a straight line and a curved line on the surface of the metal molded body to be roughened.
