Claim Text:
1. A flame-retardant thermoplastic resin composition which forms a molded article having a thin-wall portion having a thickness of not more than 1.5 mm, wherein the composition comprises: (A) a thermoplastic resin containing a repeating unit having an arylene group, an ether group, and a carbonyl group and (B) a thermoplastic fluorine-containing resin, the thermoplastic fluorine-containing resin (B) comprising a copolymer of tetrafluoroethylene and at least one member selected from the group consisting of hexafluoropropylene and a perfluoro(C a weight ratio of the thermoplastic resin (A) and the thermoplastic fluorine-containing resin (B) in the former/the latter is 95/5 to 99/1, a melt viscosity ratio of the thermoplastic resin (A) and the thermoplastic fluorine-containing resin (B) in the former/the latter is 0.3/1 to 6/1 at a temperature of 390° C. and a shear rate of 60 s the thermoplastic fluorine-containing resin (B) is dispersed in the form or particles in the thermoplastic resin (A) to form a dispersed phase, and the dispersed phase has an average particle diameter of not more than 0.7 μm.
