PROBLEM TO BE SOLVED: To provide a curable composition, which has superior workability with a low viscosity before irradiation with light and/or heat and which is rapidly cured by irradiation with light and/or heat and formed into a cured product with excellent flexibility and heat resistance, and to provide a cured product with the composition.SOLUTION: A cationic polymerizable resin comprises at least the following component (A), component (B), component (C), component (D) and component (E). Component (A) is an oxetane ring-containing (meth)acryloyl compound; component (B) is a cationic polymerizable group-containing compound; component (C) is a monofunctional radical polymerizable group-containing compound and a polyfunctional radical polymerizable group containing compound, in a compounding proportion of 5.0 mol or less of radical polymerizable groups in the polyfunctional radical polymerizable group-containing compound with respect to 1 mol of radical polymerizable groups in the monofunctional radical polymerizable group-containing compound; component (D) is a cationic polymerization initiator; and component (E) is a radical polymerization initiator. |
