Abstract
In a molded composite article, a resin member comprising a non-urethane thermoplastic resin and a resin member comprising a thermoplastic polyurethane resin are directly joined with each other. The non-urethane thermoplastic resin comprises at least one member selected from the group consisting of a polyamide component having an alicyclic ring and an amino group-containing compound, or each of the non-urethane thermoplastic resins and the thermoplastic polyurethane has a polyether segment. Even if the base resin is a non-urethane thermoplastic resin, the present invention provides a direct and firm bonding between the non-urethane thermoplastic resin member and the thermoplastic polyurethane resin member.
