摘要： A nitrile oxide compound which is a compound represented by General Formula [I], in which a melting point is 25° C. to 300° C., and an equivalent of nitrile oxide is 1.0 to 4.5 mmol/g. In the general formula, s: an integer of 1 to 4; R1 and R2: a hydrocarbon group having 4 to 10 carbon atoms or a halogenated hydrocarbon group having 4 to 10 carbon atoms; X: a divalent hydrocarbon group, —O—, —S—, or —N(R3)—; R3: a hydrogen atom or a hydrocarbon group having 1 to 6 carbon atoms; and A: an s-valent organic group.
