Polycarbonate resin composition

A polycarbonate resin composition, comprising, with respect to 100 parts by mass of an aromatic polycarbonate resin (A), 0.005 part by mass to 1 part by mass of a phosphorus-based compound (B) having an aryl group, and 0.005 part by mass to 5 parts by mass of a polyether compound (C) having a polyoxyalkylene structure,

• wherein:
• an amount of a compound having a phenol structure produced by decomposition of the phosphorus-based compound (B) 1,500 hours after standing thereof under conditions of 40° C. and a humidity of 90% is 5 mass % or less with respect to the phosphorus-based compound (B);
• when a weight of the phosphorus-based compound (B) is measured with a thermogravimetric-differential thermal analysis (TG-DTA) machine under a nitrogen atmosphere, a temperature at which the weight becomes smaller than the weight before the measurement by 2% is 340° C. or more;
• and
• the polyether compound (C) is represented by the following formula (1):
• RC3O—(RC1O)m(RC2O)n—RC4 (1)
• wherein RC1 and RC2 each represent a methylene group, an ethylene group, a trimethylene group, a propylene group, or a hexamethylene group, and RC3 and RC4 each represent a hydrogen atom, a hydrocarbon group having 1 to 30 carbon atoms, an alkanoyl group having 1 to 30 carbon atoms, an alkenoyl group having 2 to 30 carbon atoms, or a glycidyl group, and RC3 and RC4 may be identical to or different from each other.
