PROBLEM TO BE SOLVED: To provide an ABS-based resin composition for foaming which easily increases an expansion ratio in various expansion molding methods, whose product surface looks high-class, and which provides a low coefficient of linear expansion, and an expanded molding. SOLUTION: The ABS resin composition for foaming is used, which comprises an acrylonitrile-butadiene-styrene-based resin (a) and a polyethylene-based resin (b) and has melt tension (MS<SB>220</SB>) measured at 220°C and winding speed of 10 m/min, in the range of 50-150 mN.
