Abstract

A method of producing a foamed composite molded product includes fixing an exposed part of an insert material on a fixing part provided in a mold, the insert material being inserted in an in-mold foamed molded product made of a thermoplastic resin; introducing a polyurethane liquid into the mold; and producing the foamed composite molded product by foaming the polyurethane liquid in the mold. The foamed composite molded product includes an in-mold foamed molded product unit including the insert material and the in-mold foamed molded product; and a polyurethane foam. At least part of the insert material is exposed to an outside of the in-mold foamed molded product, and the in-mold foamed molded product unit and the polyurethane foam are integrated.
