An object of the present invention is to provide a curable composition that can be cured satisfactorily and can form a cured product having a high glass transition temperature as maintained and having high mechanical strength. A curable composition includes a siloxane (A), a cycloaliphatic epoxide (B), and a curing agent (C). The siloxane (A) contains at least two epoxy groups per molecule. The cycloaliphatic epoxide (B) in the curable composition is preferably a compound represented by Formula (I):
wherein X is selected from a single bond and a linkage group.
