PROBLEM TO BE SOLVED: To provide an integrated member which is provided by directly vibrating and welding a carbon fiber-reinforced thermoplastic resin molding and metal without using an adhesive and without subjecting a metal surface to a priming treatment, and has high productivity and is strongly joined to each other.SOLUTION: A welded joint in this invention is a welded joint of the carbon fiber-reinforced thermoplastic resin molding 61 that contains a carbon fiber and a thermoplastic resin as a component, and in which the carbon fiber constitutes a strip-like fiber bundle containing 1,000 to 100,000 single fibers, and content of the carbon fiber is 40-80 mass%; and the metal 62. A length axis of the carbon fiber is randomly oriented in a joint surface, and surface roughness of at least the joint surface of the metal 62 is 1-100 μm. A welded joint of the carbon fiber-reinforced thermoplastic resin molding 61 and the metal 62 is obtained by vibrating and welding the carbon fiber-reinforced thermoplastic resin molding 61 and the metal 62.SELECTED DRAWING: Figure 6 |
