Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a halogen-compound-free olefin resin foam having excellent flame retardancy and mechanical strengths and good appearance. SOLUTION: This molding is made from a composition comprising 100 pts.wt. olefin resin composition containing an ethylene/vinyl acetate copolymer and having a vinyl acetate content of 5-30 wt.%, 50-200 pts.wt. metal oxide hydrate and 5-100 pts.wt. phosphorus mixture. The phosphorus mixture comprises ammonium polyphosphate and a phosphorus compound having a 10 wt.% heat decomposition temperature lower than that of ammonium polyphosphate by at least 100 deg.C and not lower than 150 deg.C in a weight ratio of 100/1 to 1/10.
