摘要：
Extrusion molding is performed while the extrusion molding is regulated from the skin layer side so that the foaming capacity of a portion opposite to a surface of a reinforcement portion of an insert having at least one gap portion is smaller than the foaming capacity of a portion where the gap portion is filled with the foam layer when a foamable resin is foamed.
