PROBLEM TO BE SOLVED: To obtain a crosslinked olefin resin foam excellent in heat resistance, mechanical strengths, and flexibility and capable of being molded to a complicated shape. SOLUTION: This foam comprises an olefin resin having an endothermic melting peak at 140-175 deg.C (differential scanning calorimetry), a melt tension of 0.2-1.0, an expansion ratio of 25-70, and a 25% compressive strength of 0.1-0.4 kg/cm2 (at ordinary temperature), so that it is excellent in heat resistance, mechanical strengths, and flexibility, capable of having been molded in a complicated shape, and capable of providing a complicated-shape molding such as an automobile internal furnishing so as for the molding to be beautiful and have any desired shape and of providing a molding excellent heat resistance.
