1. A sheet and a base material for laminating the base material and the skin such that the base material formed into a predetermined shape and the cushion layer of the sheet-like skin having the cushion layer are in contact with each other. The method for manufacturing an interior member, wherein the skin is a sheet-like skin integrated with a foam layer formed by foaming an olefin-based resin foamable resin so as to function as a cushion layer. A foamed base material formed into a predetermined shape by foaming a foamable resin made of an olefin-based resin so as to have a mechanical strength enough to maintain the formed outer shape, and the skin is made of the olefin-based resin. A step of heating the foamed layer and the foamed base material to a temperature at which heat fusion is possible, and a step of bringing the foamed base material and the skin into close contact with each other while the skin is in a heat-fusible state by the heating. To have Method for producing a decorated member having a skin and a substrate for the symptoms.
