Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition improved in fluidity and hydrolysis resistance while maintaining transparency, heat resistance and shock resistance possessed by a polycarbonate; and to provide its resin molding.SOLUTION: The polycarbonate resin composition containing the polycarbonate (A) and a copolymer (B) having a polycarbonate structural unit (I) and a polyester structural unit (II) is used in which a terephthalic acid is indispensable to polyester (C) being a raw material of the polyester structural unit (II), the polyester is obtained by making a dicarboxylic acid component containing either or both of a succinic acid and an adipic acid, and a diol component such as ethylene glycol and 1, 2-propylene glycol react with each other, and the weight average molar weight of the copolymer (B) is 5,000 to 30,000.
