PROBLEM TO BE SOLVED: To provide a highly heat-resistant crosslinked olefin resin foam capable of affording neat molded products with no occurrence of breakage, wrinkles, etc., even if subjected to stamping molding processing in particular. SOLUTION: The crosslinked olefin resin foam 0.033-0.077 g/cm<SP>3</SP>in density is characterized by giving 120-400% in elongation at break, 0.05-0.5 MPa in maximum tensile force and 0.03-0.3 MPa in 100% modulus when subjected to a uniaxial tensile test at 175°C. Therefore, there occurs neither breakage nor unevennesses in this resin foam even if contacted with a high-temperature, molten thermoplastic resin in undergoing stamping molding in particular, obtaining neat molded products with accurate desired shape.
