PROBLEM TO BE SOLVED: To provide a polyamide-polyolefin composite molded body in which a polyamide resin structural part and a polyolefin structural part are firmly joined without using an adhesive. The polyamide-polyolefin composite molded article of the present invention comprises a polyamide resin structure part comprising a polyamide resin composition comprising a polyamide resin having a bulky alkyl group in the side chain and a modified polyolefin, and a polyolefin resin composition. Directly bonded to the polyolefin structure. As the polyamide resin having a bulky alkyl group in the side chain, for example, a copolyamide having hydrogenated dimerized fatty acid as one monomer component can be used. As the modified polyolefin, a modified polyolefin having a carboxylic acid group, a carboxylic acid metal base, a carboxylic acid ester group, an acid anhydride group or an epoxy group can be used.
