Zusammenfassung:	PURPOSE:To produce a crosslinked foamed product small in apparent density and excellent in softness and heat resistance. CONSTITUTION:A crosslinked foamed product is characterized in that a molded product comprising a foamable resin composition containing (a) an ethylenic copolymer containing ethylene and at least a radically polymerizable acid anhydride as constituting monomers and (b) a thermally decomposable organic foaming agent having a decomposition temperature of >=120 deg.C, the thermally decomposable organic foaming agent as the component (b) being contained in an amount of 0.1-40 pts.wt. per 100 pts.wt. of the ethylenic copolymer as the component (a) contains fine closed cells.
