Zusammenfassung:	Provided is a photocurable composition which less causes resin-induced swelling of molds, allows the molds to endure more satisfactorily, and has excellent economic efficiency. This photocurable composition includes components (A), (B), (C), and (D). The component (A) is present in a content of 10 to 50 weight percent of the totality of photocurable compounds contained in the photocurable composition. The component (A) is a cycloaliphatic epoxy compound represented by Formula (a). The component (B) is an oxetane compound having a solubility parameter of 9.5 (cal/cm 3 ) 1/2 or more as determined by the Fedors' method. The component (C) is a glycidyl ether epoxy compound having a molecular weight of 250 or more. The component (D) is a photoinitiator: wherein R 1 to R 18 are each, identically or differently, selected from hydrogen, halogen, a hydrocarbon group optionally containing oxygen or halogen, and optionally substituted alkoxy; and X is selected from a single bond and a linkage group.
