A polyarylate resin includes at least one type of repeating unit represented by a general formula (1), at least one type of repeating unit represented by a general formula (2), and a terminal group represented by a general formula (3). R, R, R, and Reach represent, independently of one another, a hydrogen atom or a methyl group. Rand Reach represent, independently of each other, a hydrogen atom or a Calkyl group. Rand Rmay bond together to represent a Ccycloalkylidene group. Xrepresents a divalent group represented by a chemical formula (2A), (2B), (2C), or (2D) with the proviso that when only one type of repeating unit represented by the general formula (2) is included, Xdoes not represent a divalent group represented by the chemical formula (2D). Rrepresents a chain aliphatic group having at least one fluoro group.
