PROBLEM TO BE SOLVED: To provide a manufacturing method capable of manufacturing a core material-containing polyamide resin molded product extremely high in the adhesion between a core material and a resin and excellent in adhesive strength by solving a problem wherein the resin is broken by releasing tensile stress remaining in the resin. SOLUTION: After a silane coupling agent is preliminarily applied to the surface of the core material 2, an outer peripheral part 5 is subjected to insert molding using a polyamide resin by injection molding in such a state that the core material 2 is set in a mold, and the core material 2 is subsequently heated by high frequency induction to once melt the resin at the contact part with the core material 2 before cooling and solidifying the same.
