An object of the present invention is to provide a novel electro-optic polymer. Another object of the present invention is to provide a novel electro-optical polymer having a low blending ratio of an alicyclic methacrylate monomer. In the polymer, a base polymer (a) having a reactive group (A) and an electro-optical molecule (b) having a plurality of reactive groups (B), a reactive group (A) and a plurality of reactive groups ( A polymer forming a bond (C) by reaction with B), wherein the bond (C) is a (thio) ester bond, a (thio) urethane bond, a (thio) urea bond and a (thio) amide bond And at least one polymer selected from the group consisting of |
