To provide a resin composition excellent in fluidity, good in metal die transfer, and excellent in chemical resistance and scratch resistance.

The resin composition contains a noncrystalline polyarylate resin (A) or a mixed resin of the noncrystalline polyarylate resin (A) and a polycarbonate resin (B), a polyester resin (C) composed of terephthalic acid as a main dicarboxylic acid component and 1,4-cyclohexanedimethanol as ≥60 mol% of a diol component, and a phosphorus compound (D), wherein the resin composition satisfies the following formulae (i) and (ii), and has a melt mass flow rate of 2 to 20 g/10 min as measured according to JIS K7210 at 290°C at a load of 2.16 g. {(A) + (B)}/(C)=20/80 to 80/20 (mass ratio)...Formula (i). (D)/{(A)+(B)+(C)}=0.01/100 to 0.5/100 (mass ratio)...Formula (ii).
