A polycarbonate resin composition may include a first polycarbonate resin and a second polycarbonate resin, which a molded article may include, and a multilayer body may have a resin layer A including the polycarbonate resin composition and a resin layer B including a resin different from the resin layer A. The first polycarbonate resin may include 40% by weight or more of a structural unit of formula (1) The second polycarbonate resin may include less than 40% by weight of the structural unit of formula (1). The weight ratio of the first polycarbonate resin to the second polycarbonate resin, the first polycarbonate resin/the second polycarbonate resin, may be in a range of from 55/45 to 99/1. The polycarbonate resin composition may have two or more glass transition temperatures.
