Abstract

A multilayer composite body in which a shaped metal article, a thermosetting resin layer, a modified polyolefin resin layer, and a polypropylene-based resin composition, or a PP-based GFRTP are laminated in the order of description. A multilayer composite body of a metal and a resin is obtained which excels in a fixing strength (shear breaking stress) between the shaped metal article and the molded article of the polypropylene-based resin composition. The thermosetting resin layer is composed mainly of a urethane resin or an epoxy resin. The polypropylene-based resin composition is molded by an injection molding. The modified polyolefin resin forming the modified polyolefin resin layer includes one or two or more of non-chlorinated modified polyolefin resins having a weighted average of melting points of 70° C. to 110° C., as determined with a differential scanning calorimeter (DSC).
