PROBLEM TO BE SOLVED: To provide a curing composition, a curing method of the composition and a cured product prepared by the method, which solve the conventional problems, deterioration of physical properties of the cured product due to a residual monomer and exuding or scattering out of a residual monomer from the cured product, that occur when a cyclic ether compound and a cationically polymerizable compound having ethylenically unsaturated bonds are copolymerized, and consequently the cationically polymerizable residual monomer having an ethylenically unsaturated bond remains unreacted in the cured product or the polymerized product. SOLUTION: The curing composition consists of: (A) a cationically- polymerizable compound having an ethylenically unsaturated bond; (B) a compound having a cyclic ether structure; (C) a compound having a hydroxy group in a molecule; and (D) a cationic polymerization catalyst. In the method of curing, the curing composition provided is either heated or irradiated with activation light at the temperature range of 50 to 200 deg.C for 0.1 second to 50 hours. The cured product is prepared by the method provided.
