To provide a method for producing a1,3-diadamantyl ester compound, by which the 1,3-diadamantyl ester compound can efficiently be produced from raw materials except a 1,3-diadamantanediol compound, and to provide a method for producing a 1,3-diadamantanediol compound, by which the 1,3-diadamantanediol compound can efficiently be produced by a reaction under the atmospheric pressure.

This method for producing the 1,3-diadamantyl ester compound comprises mixing and reacting a 1,3-dihalogenated adamantane compound with a carboxylic acid compound such as acetic acid and the metal salt of the carboxylic acid compound such as zinc acetate or a transition metal oxide such as zinc oxide. The method for producing the 1,3-diadamantanediol compound comprises reacting the ester bonds of the produced 1,3-diadamantanediol compound with water or the like in the presence of an acid or a base to break the ester bonds and simultaneously introduce hydroxyl groups.
