PROBLEM TO BE SOLVED: To manufacture polyolefinic resin foam excellent in compression recovery capacity. SOLUTION: A mixture, which contains 100 pts.wt. of a polyolefinic resin, 5-30 pts.wt. of a thermally decomposable foaming agent and 1-5 pts. wt. of an alkoxysilane compound having an acryloyl or methacryloyl group in its molecule, is molded at temperature lower than the decomposition temperature of the foaming agent to obtain a molded article which is then irradiated with ionizing radiation. This molded article is heated to the decomposition temperature of the foaming agent and further immersed in a heating medium to manufacture the polyolefinic resin foam.
