Curable resin, curable resin composition, and cured product

Abstract

An object is to provide a cured product and the like with excellent fire retardancy, heat resistance, and dielectric properties by using a curable resin having a specific structure and a curable resin composition containing the curable resin, a radical polymerization initiator, and a fire retardant. Specifically provided are a curable resin represented by General Formula (1) and a curable resin composition containing the curable resin, a radical polymerization initiator (B), and a fire retardant (C): in the formula, Ra and Rb each independently represent an alkyl group, an aryl group, an aralkyl group, or a cycloalkyl group with a carbon number of 1 to 12; k indicates an integer of 0 to 3; X represents a hydrocarbon group; and Y represents General Formula (2) or (3) below: in the formula, Z represents an alicyclic group, an aromatic group, or a heterocyclic group.
