Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition giving a molded article composed of the resin composition excellent in transparency, color tone, weatherability and wet heat resistance, excelling in heat stability and releasability on molding, and reduced of the formation of a mold deposit.SOLUTION: The resin composition includes: (A) 100 pts.wt. thermoplastic resin (component A); (B) 0.01-5 pts.wt. bisbenzoxadinone compound (component B) which is represented by formula (1) and has (i) purity of 98% or higher, (ii) a content of a compound represented by formula (2) of less than 0.15 wt.%, (iii) a maximum peak in the light reflectance measurement in the visible light range in the state of a powder in the range of 380-480 nm and a maximum light reflectance of 100% or more, (iv) a sodium metal content of less than 50 ppm, and (v) a YI value of not greater than 10; and (C) 0.01-1 pt.wt. fatty acid ester compound (component C) which is an ester of a polyhydric alcohol and an aliphatic carboxylic acid and has a 5% weight reduction temperature in TGA (thermogravimetric analysis) of 250-360°C and an acid value of 4-20.
