Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition including a plant-derived raw material and having excellent mechanical strength, heat resistance, a small refractive index, a fine color tone and excellent transparency. SOLUTION: The polycarbonate resin composition includes a phosphorus-based compound and/or a hindered phenol-based compound (b) and an acidic compound (c) in a polycarbonate resin (a) including at least a constitutional unit derived from a dihydroxy compound represented by general formula (1), wherein the content of the compound (b) is 0.001-10 pts.wt. based on 100 pts.wt. of the resin (a), and the content of the compound (c) is
