PROBLEM TO BE SOLVED: To provide a crosslinked polyolefin resin foam which yields an expandable sheet showing an excellent extrusion property, shows an excellent stability at normal pressure expansion, contains fine expanded cells at either a low or high expansion ratio and has a substantially uniform product appearance and an excellent thickness uniformity. SOLUTION: The crosslinked polyolefin resin foam has a polyolefin resin (resin A) having an MFR of from 0.1 to 3 g/10 min and an extremely high molecular polyethylene (resin B1) having an intrinsic viscosity, measured in a decalin solvent at 135 deg.C, of from 5 to 40 dl/g. Here, the weight ratio of resin A to resin B1 is from 100:(0.01-20).
