PROBLEM TO BE SOLVED: To provide a curable epoxy resin film which is not only high in transparency, curability, and refractive index but also excellent in flexibility and is capable of being put into practical use in optical fields requiring flexibility. SOLUTION: The curable epoxy resin film is prepared by forming a resin composition containing a phenoxy resin, a room temperature solid linear bisphenol epoxy resin, a room temperature liquid bisphenol epoxy resin, and a cationic polymerization initiator into a film.
