PROBLEM TO BE SOLVED: To provide a method for producing a vinyl acetate-based resin crosslinked foam by which a foaming agent is dispersed homogeneously, and few coarse bubbles in the inside of the foam and few pinholes in the surface layer part of the foam are formed. SOLUTION: The method for producing the resin composition for the polyolefin-based resin crosslinked foam includes melting and kneading a resin component (D) comprising 10-90 wt.% polyolefin-based resin (C) and 90-10 wt.% foaming agent-containing master batch (B) obtained by formulating 15-100 pts.wt. foaming agent with 100 pts.wt. ethylene-vinyl acetate copolymer (A), and melting and kneading the formulated product at a temperature from the melting point of the ethylene-vinyl acetate copolymer (A) to the temperature 50°C lower than the melting point while adding shear force, at a temperature from the melting point of the polyolefin-based resin (C) to the temperature 50°C lower than the melting point while adding shear force.
