Claim:
1. A cladding material of an optical waveguide, comprising: a polymer compound including a triarylamine structure; and a nonlinear optical compound, wherein the polymer compound including the triarylamine structure has a repeating unit of formula (2) or formula (3): in formula (2) and formula (3), Ar 2 to Ar 4 are each independently any one of divalent organic groups of formula (4) to (8) below; in formula (2), Z 1 is a monovalent organic group of formula (9) below, and Z 2 is a hydrogen atom; and in formula (3), R 15 to R 18 are each independently a hydrogen atom (provided that R 15 and R 18 are not simultaneously hydrogen atoms), or a C 1-5 hydroxyalkyl group, in the formulas, R 19 to R 52 are each independently a hydrogen atom, a C 1-5 alkyl group, an epoxy group, a carboxy group, a hydroxy group, a C 1-5 alkoxy group, or a halogen atom, in the formula, R 53 to R 57 are each independently a hydrogen atom (provided that R 53 to R 57 are not simultaneously hydrogen atoms), a C 1-5 hydroxyalkyl group, an OR 77 group, a COR 77 group, a COOR 77 group, or an NR 77 R 78 group (in these formulae, R 77 is a C 1-5 hydroxyalkyl group and R 78 is a hydrogen atom).
