Abstract: The present invention provides a cured product obtained by curing a curable composition including a compound represented by General Formula 1, in which a birefringence Δn (587 nm) is 0.00≤Δn (587 nm)≤0.01. Pol1-Sp1-L1-Ar-L2-Sp2-Pol2  (General Formula 1) In the formula, Ar represents a divalent group containing a ring structure selected from the group consisting of a quinoxaline ring and a quinazoline ring; L1 and L2 each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp1 and Sp2 each represent a single bond or a divalent linking group; Pol1 and Pol2 each represent a hydrogen atom or a polymerizable group; and the compound represented by General Formula 1 has at least one polymerizable group. The cured product of the present invention has a small Abbe number (νd) and a large partial dispersion ratio (θg, F), and is therefore useful for production of optical members.
