摘要： A formed product produced by using a thermoplastic resin composition comprising a polycarbonate resin with a repeating unit (A) represented by the following general formula (1) and a repeating unit (B) represented by the following general formula (2). R 1 and R 2 independently denote a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group. The alkyl groups in R 1 and R 2 may be bonded together to form a ring. R 3 and R 4 independently denote a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aryl group. X denotes a single bond or a divalent organic group represented by the following general formula (3). R 6 to R 9 independently denote a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms or a substituted or unsubstituted aryl group. R 5 denotes a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group.
