A polyarylate resin is represented by general formula (1) shown below. In general formula (1), R 1 , R 2 , R 3 , and R 4 each represent, independently of one another, a hydrogen atom or a methyl group. r and s each represent an integer of at least 0 and no greater than 49. t and u each represent an integer of at least 1 and no greater than 50. r+s+t+u=100. r+t=s+u. r and t may be the same as or different from each other. s and u may be the same as or different from each other. X represents a divalent group represented by chemical formula (2A), (2B), (2C), or (2D). Y represents a divalent group represented by chemical formula (4A), c (4B), or (4C). X and Y are different from each other. |
