  A polycarbonate resin which is reduced in the change of hygroscopic-expansion coefficient with changing environmental humidity, is inhibited from warping, and is suitable for use as an optical material is provided with excellent productivity. The polycarbonate resin is obtained by reacting an aromatic dihydric phenol compound (2,2-bis(4-hydroxyphenyl)propane, etc.), a compound forming a carbonic ester (phosgene, etc.), and a chain terminator represented by the following general formula (A) (dodecyl 4-hydroxybenzoate, etc.). (In the formula (A), n is an integer of 10 - 20.)
