Abstract: PROBLEM TO BE SOLVED: To provide a foam structure having a high degree of freedom for various kinds of processings according to heating and a polyolefin resin composition having a foaming ability capable of selecting a method for processing. SOLUTION: This polyolefin resin composition is obtained by melting and kneading (A) a polyolefin resin having =100 deg.C and (C) a thermal decomposition type chemical foaming agent at a temperature not lower than the melting point Tma and lower than the decomposition starting temperature of the chemical foaming agent and then processing the kneaded material into a boardlike, a chiplike or a powdery form (D). The foam structure of the form is obtained by inserting the polyolefin resin composition into a prescribed space or joining the polyolefin resin composition to another article and thermally foaming the joined material in the state.
