PROBLEM TO BE SOLVED: To obtain a polyarylate having extremely high heat resistance and elastic modulus. SOLUTION: This polyarylate contains 10-90% repeating unit of formula (1) (wherein A is at least one kind selected from an aliphatic hydrocarbon group which may have a 4-15C branch and an alicyclic hydrocarbon group which may have a 4-15C branch; and R<SP>1</SP>to R<SP>8</SP>are the same or different and are each hydrogen or a 1-6C hydrocarbon group).
