PROBLEM TO BE SOLVED: To obtain a vinyl chloride resin composition which has a lower linear expansion coefficient compared with the conventional products and has superior impact resistance, and to provide a molding therefrom. SOLUTION: The resin composition is obtained by incorporating 10-60 pts.wt. of a needle-shaped or plate-shaped inorganic substance into 100 pts.wt. of a vinyl chloride resin (A+B) mentioned below. Herein, the vinyl chloride resin comprises a vinyl chloride resin(A) obtained by graft polymerization of 70-99 wt.% of a vinyl monomer having vinyl chloride as the major component onto 1-30 wt.% of an elastomer component (a) having an average particle size of <0.15μm and a vinyl chloride resin (B) obtained by graft polymerization of 70-99 wt.% of a vinyl monomer having vinyl chloride as the main component onto 1-30 wt.% of an elastomer component (b) having an average particle size of≥0.2μm, and has a weight ratio (A)/(B), in the elastomer components, of 30/70-95/5.
