Zusammenfassung:	[Object] Provided is a reinforcing agent for resin that is able to impart excellent impact resistance, resistance to thermal coloration, and resistance to moist heat to a polycarbonate resin. [Solving Means] Disclosed is a reinforcing agent for polycarbonate resin which includes a rubber-like graft polymer, in which a quantity of the YI value that is increased by a heat treatment at a temperature of 140°C for 12 hours and measured for a molded article obtained by molding 3 parts by mass of the reinforcing agent for polycarbonate resin and 97 parts by mass of an aromatic polycarbonate resin having a viscosity average molecular weight of 24,000 under a specific condition is 36 or less and a quantity of the MFR value increased by a heat treatment for 60 hours under a condition of a temperature of 120°C and a relative humidity of 100% is 3 or less. Disclosed is also a resin composition including the reinforcing agent for polycarbonate resin.
