Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a resin compsn. comprising an olefin-derived thermoplastic elastomer which has good foaming characteristics and can be used for manufacturing a foamed molded article having a soft touch, a foamed molded article therefrom, a manufacturing method therefor as well as a laminate obtd. by using the foamed molded article. SOLUTION: This resin compsn. for molding a foamed article comprises (a) 10-90 wt.% of an olefin-derived thermoplastic elastomer and (b) 90-10 wt.% of a polyolefin resin having a crystallization temp. of 0-130 deg.C (wherein the total of (a) and (b) is 100 wt.%). The resin compsn. and a foaming agent are injected into the cavity of a mold, followed by enlarging the vol. of the cavity to allow foaming. Accordingly, a foamed molded article is manufactured. A laminate is obtd. which comprises a skin member having a transparent resin layer or a decorative film layer including a transparent resin layer and a foaming layer, as well as a substrate wherein the transparent resin layer has a haze of
