A resin composition includes a polyester resin, an alloyed resin of a polycarbonate resin and an acrylonitrile-butadiene rubber-styrene resin, and an acrylic block copolymer containing a polymer block containing an acrylic acid ester monomer unit and a polymer block containing a methacrylic acid ester monomer unit, wherein a weight ratio of a content of the polyester resin and a content of the alloyed resin is in a range of 5:95 to 50:50, and wherein a content of the acrylic block copolymer is in a range of 0.5% by weight to 10% by weight with respect to a total of the content of the polyester resin and the content of the alloyed resin.
