PROBLEM TO BE SOLVED: To provide a nonpoisonous vinyl chloride resin composition for injection molding which is excellent in heat stability, heat resistance and moldability and a molded product using the same. SOLUTION: The vinyl chloride resin composition for injection molding contains (a) 100 pts.wt. vinyl chloride resin with an average polymerization degree of 400-1,000, (b) 0.5-5 pts.wt. Ca-Zn heat stabilizer, (c) 0.3-3 pts.wt. at least one selected from pentaerythritol, dipentaerythritol and fatty acid esters thereof with a melting point of≥100°C and (d) 0.1-1 pts.wt.β-diketone compound.
