The present invention provides a thermoplastic resin having a high refractive index, a low b value, and high humidity and heat resistance, an optical lens using the thermoplastic resin, and the like. According to one embodiment, a thermoplastic resin containing a structural unit represented by the following general formula (1) is provided. (R 1 and R 2 in formula (1) each independently represent a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, an alkyl group having 1 to 6 carbon atoms, a monocyclic or polycyclic carbon Aryl with 6 to 36 atoms, monocyclic or polycyclic heteroaryl with 5 to 36 ring atoms, alkenyl with 2 to 6 carbon atoms, alkoxy group with 1 to 6 carbon atoms, or carbon Aralkyl with 7 to 17 atoms, in the above heteroaryl, 1, 2, 3 or 4 of the ring atoms are selected from nitrogen, sulfur and oxygen, the other ring atoms are carbon, X, a and b are respectively as follows described in this application specification.) |
