The polycarbonate resin composition

Object of the present invention is to obtain heat resistance, excellent impact resistance, high surface hardness and a polycarbonate resin. A resin composition comprising a polycarbonate, which is a polycarbonate resin comprising (A) and the aromatic polycarbonate resin (B) polycarbonate resin composition (X-), the polycarbonate resin (A) containing structural unit (a) derived from a dihydroxy compound, the dihydroxy compound having the portion of the following formula (1) in a part of the structure, wherein the aromatic polycarbonate resin (B) has a reduced viscosity of 0.55 dl / g or less, the polycarbonate resin composition (X) in the aromatic polycarbonate resin proportion (B) is 30 wt% or more, the polycarbonate resin composition (X) of the total light-permeable over 90% or less.
