Provided are a polyphenylene ether resin composition having excellent fluidity and heat resistance, and a vehicle lighting fixture bezel formed of this resin composition and having light weight, excellent external appearance, and low water absorbency. The resin composition contains: (A) 42-57 mass % of a polyphenylene ether resin having a reduced viscosity of 0.39-0.43 dL/g (in chloroform solvent at 30&#xb0; C.); (B) 11-26 mass % of a polyphenylene ether resin having a reduced viscosity of 0.31-0.34 dL/g (in chloroform solvent at 30&#xb0; C.); (C) 9-15 mass % of a block copolymer including a vinyl aromatic hydrocarbon polymer block (c1) and a hydrogenated conjugated diene polymer block (c2); and (D) 15-23 mass % of a homopolymer of a vinyl aromatic hydrocarbon. The (C) block copolymer includes 62-70 mass % of vinyl aromatic hydrocarbon-derived monomer units, has a weight-average molecular weight Mw of 50,000-70,000, and has a molecular weight distribution Mw/Mn (Mn is number-average molecular weight) of 1.00-1.30.
