PROBLEM TO BE SOLVED: To provide an injection molded product having heat resistance and good appearance. SOLUTION: The injection molded product is obtained by using a resin composition composed of (A) a lactic acid-based resin having≥0.1% and≤3.0% ratio of D-lactic acid, (B) an aromatic polycarbonate-based resin having≥10 and≤50 melt flow rate measured under 1.2 kg load at 300°C and (C) inorganic fine particles having≥2.0 refractive index, wherein the ratio of the aromatic polycarbonate-based resin (B) is≥10 mass% and <50 mass% and the ratio of the inorganic fine particles is≥0.1 mass% and≤10 mass%. The relative degree of crystallizationλc(A) of the lactic acid-based resin (A) constituting the injection molded product, the crystallization heat quantityΔHc(A) of the lactic acid-based resin (A) and crystal melt heat quantityΔHm(A) satisfy the formulaχc(A)=[ΔHm(A)-ΔHc(A)]/ΔHm(A)≥0.90.
