PROBLEM TO BE SOLVED: To develop a resin composition that has excellent antistatic properties, high balance between impact strength and modulus of elasticity and a practical heat distortion temperature without losing moldability, colorability and lightness essential to a styrene-based resin and is practically applied to a material such as a transportation material for electronic parts. SOLUTION: The resin composition comprises (A) a rubber-reinforced styrene-based resin, (B) a polyolefin-polyether block copolymer and (C) a hydrogenation product of a polystyrene-polybutadiene block copolymer in the weight ratios of the components (A), (B) and (C) satisfying numerical expression (1): 0.80≤(A)/ä(A)+(B)}≤0.95, numerical expression (2): 0.05≤(B)/ä(A)+(B)}≤0.20 and numerical expression (3): 0.20≤(C)/(B)≤1.00.
