Abstract
A sheet formed from carbon fiber reinforced thermoplastic resin with high moldability, and a production method of said resin is provided. This sheet is formed from a carbon fiber reinforced thermoplastic resin that contains carbon fibers, dichloromethane, and a thermoplastic resin containing at least one of a polycarbonate resin and a polyarylate resin. The aforementioned at least one of a polycarbonate resin and a polyarylate resin has a terminal structure derived from a monohydric phenol represented by formula (1) and a constituent unit derived from a dihydric phenol, and the content of the dichloromethane contained in the sheet is 10-10,000 ppm by mass. (In formula (1), Rrepresents an alkyl group with 8-36 carbons, or an alkenyl group with 8-36 carbons, and R-Rindependently represent a hydrogen, a halogen, an alkyl group with 1-20 carbons optionally having a substituent, or an aryl group with 6-12 carbons optionally having a substituent.)
