Abstract
A composite molding is formed by welding and joining a foam to a substrate made of a synthetic resin, the foam including a hard skin layer and a foamed layer formed by foaming a foamable synthetic resin in an unhardened state within the skin layer as the pressure of a cavity is decreased, wherein the skin layer includes a cover covering the foamed layer and a collar projecting outward from the edge of the cover on the substrate side while being directly welded and joined to the surface of the substrate. Therefore, the edge of the skin layer on the substrate side can be adequately hardened, thereby enabling adequate formation of the foamed layer and adequate welding between the foam and the substrate.
