The present invention provides a cured resin that is excellent in optical properties such as transparency, (long-term) light resistance, long-term heat resistance, dielectric constant and mechanical properties, and is suitably used in the field of electronic and optical materials, and the cured resin To provide an adamantane derivative that can be used in production and that can be applied in various ways according to the purpose of use of the cured resin. The general formula (I) Wherein R 1 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a trifluoromethyl group, X represents a cyclic ether group capable of cationic ring-opening polymerization, and k represents an integer of 0 to 7 M and n independently represent an integer of 1 or more, and m + n ≦ 4.) An adamantane derivative characterized by having a structure represented by the following formula: a method for producing the adamantane derivative; and a resin composition and a resin cured product using the adamantane derivative.
