To provide a polycarbonate resin composition capable of blocking ultraviolet light as well as light in a wavelength of 400 to 420 nm closer to the visible light, while causing no problem of gas generation at the time of molding.SOLUTION: The polycarbonate resin composition contains, with respect to 100 parts by weight of polycarbonate resin (A), 0.08 to 1 part by weight of an ultraviolet absorber (B1) which has 360 nm or more and less than 375 nm of a maximum absorption wavelength of an absorption curve obtained in conformity with JIS K7105, or 0.01 to 0.5 part by weight of a stabilizer (C).SELECTED DRAWING: None 【課題】紫外光に加え、より可視光側の４００〜４２０ｎｍの波長光のカットが可能で、且つ、成形時のガス発生の問題がないポリカーボネート樹脂組成物を提供する。【解決手段】ポリカーボネート樹脂（Ａ）１００質量部に対し、ＪＩＳ Ｋ７１０５に準拠して求める吸収曲線の最大吸収波長が３６０ｎｍ以上３７５ｎｍ未満である紫外線吸収剤（Ｂ１）を０．０８〜１質量部、及び安定剤（Ｃ）を０．０１〜０．５質量部含有することを特徴とするポリカーボネート樹脂組成物。【選択図】なし
