A polycarbonate copolymer contains: 0.1 to 50 mol% of a monomer unit represented by the following formula (1); and a monomer unit represented by the following formula (2). In the polycarbonate copolymer, the content of biphenols having a structure represented by the following formula (3) is 90 mass ppm or less.
In the formula, R1 and R2 each independently represent a hydrogen atom, an aliphatic hydrocarbon group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms or a halogen atom.
In the formula: R3 and R4 each independently represent a hydrogen atom, an aliphatic hydrocarbon group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms or a halogen atom; and X represents any one of bonding groups represented by -O-, -S-, - SO-, -SO2-, -CO- and 9,9- fluorenylidene group.
In the formula, R1 and R2 each independently represent a hydrogen atom, an aliphatic hydrocarbon group having 1 to 6 carbon atoms, an aryl group having 6 to 12 carbon atoms or a halogen atom.
