PROBLEM TO BE SOLVED: To provide an optical member having excellent heat resistance and rigidity and less changes in the appearance such as internal haze. SOLUTION: The optical member is made of an aromatic polycarbonate resin comprising a component expressed by general formula [1] and a specified dihydroxy component and has≤10 ppm content of alkali metal compounds. As the optical member made of the aromatic polycarbonate resin has high transmitting property, excellent heat resistance and rigidity, and less changes in the appearance such as haze, the resin is suitable for an optical member such as a lens, prism, optical fiber, optical film, liquid crystal display, light diffusing plate in a backlight system of a liquid crystal TV set, and light guide plate used for a scanner.
