摘要： An object of the present invention is to provide a composite foam having a high compressive strength. A polyolefin resin is melted and kneaded with a modifying monomer to react them. A thermally decomposable chemical foaming agent is added to the obtained modified resin, and the mixture is kneaded. The obtained foamable resin composition is shaped into a sheet. A sheet-like facing material (3) having a strength sufficient to inhibit the foamable sheet from expanding in in-plane directions during thermal foaming is laminated on at least one side of the foamable sheet. The obtained foamable composite sheet is thermally foamed to produce a composite foam (1) having rugby-ball-shaped cells (2) oriented in the direction of the sheet thickness.
