1. A resin composition comprising:
a polycarbonate resin; a polyethylene terephthalate resin; a glycidyl-group-containing polyethylene copolymer; a vinyl acetate-ethylene copolymer; an organic phosphorus flame retardant; and a flame-retardant anti-drip agent, wherein the amounts of the polycarbonate resin and polyethylene terephthalate resin are approximately from 60 mass % to 90 mass % and approximately from 10 mass % to 40 mass % relative to the total amount of the polycarbonate resin and the polyethylene terephthalate resin, respectively, the glycidyl-group-containing polyethylene copolymer contains a glycidyl-group-containing (meth)acrylate unit and an ethylene unit, the glycidyl-group-containing (meth)acrylate unit content in the glycidyl-group-containing polyethylene copolymer is approximately in the range of 2 mass % to 20 mass %, and the glycidyl-group-containing polyethylene copolymer is any one of a polyethylene copolymer having a glass transition temperature of approximately not more than 0° C. and a copolymer in which a polymerizable vinyl monomer has been graft-polymerized with the main chain of a polyethylene copolymer containing a glycidyl-group-containing (meth)acrylate unit and an ethylene unit. |
