An optical resin material for chromatic aberration correction is provided including at least 5% by mass of a compound (component A) represented by formula (1) or formula (3), in which R1 to R6 each independently represent a structure represented by formula (2), in which the broken line represents a binding site; n1 represents an integer of 0 to 3; n2 represents an integer of 0 or 1; n3 represents an integer of 0 to 4; R7 represents hydrogen, an acryl group, a methacryl group, a cyanoacryl group, a cyclic ether group, an allyl group, a propargyl group, a hydroxy group, an isocyanate group, chlorine, or an optionally branched alkyl group having 1 to 8 carbon atoms; and X represents an alkylene glycol chain having 2 to 7 carbon atoms or a lactone-modified ketone chain, in which R1 to R6 each independently represent a structure represented by formula (2).
An optical element obtained by curing an optical resin material for chromatic aberration correction, comprising 10% by mass or more of a compound (component A) represented by general formula (1) or general formula (3), and a polymerizable composition (component B);
