Abstract:
A polycarbonate resin composition pellet contains a polycarbonate resin (A), an aromatic compound (B) represented by general formula (1) below, and a phosphorus-based stabilizer (C), the aromatic compound (B) being contained in the pellet in an amount of 0.001% to 1% by mass, the phosphorus-based stabilizer (C) being contained in the pellet in an amount of 0.003% to 0.5% by mass: (where Y is a hydrogen atom or an organic group that does not contain any of nitrogen, sulfur, and halogen elements, when Y is a hydrogen atom, X is an alkyl group or an optionally substituted aryl group, when Y is an organic group, X is an organic group that does not contain any of nitrogen, sulfur, and halogen elements, g is 1 or 2, n is 0 to 5, k is 1 to 4, and k+n is 6 or less.)
