Abstract
The present invention provides a polycarbonate resin composition containing a polycarbonate resin (A), a flame retardant (B), and a fluoropolymer (C), said polycarbonate resin composition being characterized in that the fluidity of the fluoropolymer (C), as measured using a Koka flow tester (under the conditions of a measurement temperature of 400° C., a measurement load of 0.98 MPa, and a die hole diameter of 2.1 mm), is 0.1×10−3 cm3/sec or greater. The present invention also provides a sheet and a film.
