An oxime ester compound is useful as a photopolymerization initiator used in a polymerizable composition. A photopolymerization initiator contains the oxime ester compound. The oxime ester compound contains, in the same molecule: a group represented by the following Formula (I); and a photoradical cleavable group containing no oxime ester group.

An novel epoxy compound is represented by the general formula (I) and has a benzo- or naphtho-cycloalkane skeleton: X, Y, and Z each independently represent an alkyl group having 1-10 carbon atoms and optionally substituted with a halogen atom, an aryl group having 6-20 carbon atoms and optionally substituted with a halogen atom, an arylalkyl group having 7-20 carbon atoms and optionally substituted with a halogen atom, a heterocyclic group having 2-20 carbon atoms and optionally substituted with a halogen atom, or a halogen atom; k represents a number of 0-4; p represents a number of 0-8; r represents a number of 0-4; n represents 0-10; x represents a number of 0-4; y represents a number of 0-4; a sum of x and y is 2-4; and an optical isomer that exists when n is not 0 may be of any type.
