Abstract
A nonlinear optically active copolymer having satisfactory orientation characteristics and able to allow for reduction in heat-induced orientation relaxation of a nonlinear optical material, and a nonlinear optical material obtained using the copolymer. The copolymer including at least a repeating unit A having adamantyl group and a repeating unit B having a nonlinear optically active moiety in one molecule, and an organic nonlinear optical material including the copolymer as a component.
