PROBLEM TO BE SOLVED: To directly and strongly join, by a simple method, a polyamide resin member and a thermoplastic polyurethane resin member both of which are mutually different in properties. SOLUTION: In the composite molded product wherein the resin member constituted of a polyamide resin and the resin member constituted of the thermoplastic polyurethane resin member are joined directly, a polyamide resin constituted of a polyamide component having an aliphatic ring is used as the polyamide resin and the polyamide component may be an alicyclic polyamide resin, an alicyclic polyamide elastomer or the like or may be a combination of an alicyclic polyamide component (especially a polyamide component obtained using an alicyclic diamine) such as an alicyclic polyamide resin, an alicyclic polyamde elastomer or an alicyclic polyamide oligomer or the like and a non-alicyclic polyamide component. The composite molded product can be manufactured by heating either one of the polyamide resin and the thermoplastic polyurethane resin to join both resins. COPYRIGHT: (C)2005,JPO&NCIPI
