Abstract:
The polycarbonate resin of the invention includes a first structural unit derived from a dihydroxy compound represented by a general formula (1), a second structural unit derived from a dihydroxy compound represented by a general formula (2), and a third structural unit derived from at least one dihydroxy compound selected from the group consisting of a dihydroxy compound represented by a general formula (3), a dihydroxy compound represented by a general formula (4), a dihydroxy compound represented by a general formula (5), and a dihydroxy compound represented by a general formula (6), and in which the first structural unit derived from a dihydroxy compound represented by the general formula (1) accounts for 18% by mole or more of the polycarbonate resin. The above general formulae (1) to (6) are described in the specification of the present application.
