Provided are a curable composition that provides a cured product with a high glass transition temperature and excellent adhesion, a cured product production method, and a cured product therefrom. The curable composition includes: 30–99 parts by mass of a cationically polymerizable component (A); 0.1–10 parts by mass of a cationic polymerization initiator (B); 0–55 parts by mass of a radically polymerizable component (C); 0–10 parts by mass of a radical polymerization initiator (D); and 1–30 parts by mass of a polymer (E) having a weight-average molecular weight of 1,000–30,000 and selected from a polymer obtained from the monomer represented by formula (I) (in the formula, X is a C1–7 alkyl group, or the like) and a polymer obtained from the monomer represented by formula (II) (in the formula, R 1 represents a hydrogen atom, or the like, and X' is a C1–7 alkyl group, or the like). Component (A) includes a glycidylated product of a polyhydric alcohol having a molecular weight of at least 200, and an alicyclic epoxy compound. Component (C) is a compound which has an epoxy group and the like. |
