摘要： The purpose of the present invention is to provide a polycarbonate resin which has high fluidity and with which mold fouling such as mold deposits, etc., can be reduced. The polycarbonate resin according to the present invention has a terminal structure represented by general formula (1), and a viscosity-average molecular weight of 10,000-18,000, wherein the contained amount of low-molecular-weight carbonate compounds having a molecular weight of 1,000 or less contained in the polycarbonate resin is less than 1 mass %.
