PROBLEM TO BE SOLVED: To obtain a crosslinked a polyolefin-based resin foam which has excellent heat resistance, excellent high-temperature elongation and high- temperature strength at break even in the case of a high expansion ratio and a low apparent density, causes no blister phenomena, no pockmark phenomena and no tearing in pieces in molding and processing and is suitably usable for any molding method of vacuum forming, compression molding or hot stamping molding. SOLUTION: This crosslinked polyolefin resin foam comprises a resin component composed of 40-99.5 wt.% of a polypropylene-based rein and 0.5-60 wt.% of a polyethylene-based resin containing a polyethylene component having >=1,000,000 molecular weight in which the amount of the polyethylene component having >=1,000000 molecular weight in the polyethylene-based resin is 0.5-20 wt.% in the whole resin component. |
