Claim:
A polycarbonate resin which contains a structural unit represented by the following formula (I) and a structural unit represented by the following formula (II): wherein: in the above formula (I), R 1 to R 6 , each independently, represent a group selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, an alkyl group having 1-9 carbon atoms, an aryl group having 6-12 carbon atoms, an alkoxy group having 1-5 carbon atoms, and an aralkyl group having 7-17 carbon atoms; when R 1 to R 6 are a group containing a carbon atom, the carbon atom can be bonded with a substituent selected from the group consisting of an alkyl group having 1-5 carbon atoms, an alkoxy group having 1-5 carbon atoms, fluorine, chlorine, bromine and iodine; and “a” represents an integer of not less than 5; wherein: in the above formula (II), R 7 to R 10 , each independently, represent a group selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, an alkyl group having 1-9 carbon atoms, an aryl group having 6-12 carbon atoms, an alkoxy group having 1-5 carbon atoms, and an aralkyl group having 7-17 carbon atoms; when R 7 to R 10 are a group containing a carbon atom, the carbon atom can be bonded with a substituent selected from the group consisting of an alkyl group having 1-5 carbon atoms, an alkoxy group having 1-5 carbon atoms, fluorine, chlorine, bromine and iodine; and “X” represents a divalent group selected from the structures represented by the following formula (III): wherein: in the above formula (III), each of R 11 and R 12 represents independently a group selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, an alkyl group having 1-9 carbon atoms, an alkoxy group having 1-5 carbon atoms and an aryl group having 6-12 carbon atoms, or a group forming a carbon ring having 5-12 carbon atoms or a heterocycle having 5 to 12 elements wherein R 11 and R 12 are bonded with each other; when R 11 and R 12 are a group containing a carbon atom, the carbon atom can be bonded with a substituent selected from the group consisting of an alkyl group having 1-5 carbon atoms, an alkoxy group having 1-5 carbon atoms, fluorine, chlorine, bromine and iodine; each of R 13 and R 14 independently represents a group selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, an alkyl group having 1-9 carbon atoms, an alkoxy group having 1-5 carbon atoms and an aryl group having 6-12 carbon atoms; when R 13 and R 14 are a group containing a carbon atom, the carbon atom can be bonded with a substituent selected from the group consisting of an alkyl group having 1-5 carbon atoms, an alkoxy group having 1-5 carbon atoms, fluorine, chlorine, bromine and iodine; R 15 represents an alkylene group having 1-9 carbon atoms; “b” represents an integer of 0-20; and “c” represents an integer of 1-500.
