PROBLEM TO BE SOLVED: To provide a resin composition in which practical rigidity, impact strength and excellent flowability are combined and the original moldability and mechanical properties of a styrenic resin are maintained while reducing an amount of the styrenic resin used. SOLUTION: The resin composition includes: 93-5 wt.% of styrenic resin (A); 2-30 wt.% of block copolymer (B) produced by the living radical polymerization of a styrenic monomer and (meth)acrylate monomer; and 5-93 wt.% of polylactic acid-based resin (C), wherein the block copolymer (B) is a copolymer having [weight of styrenic monomer]/[weight of the (meth)acrylate monomer] of 15/85 to 85/15 and a number-average molecular weight of 30,000 to 80,000.
