To provide a curable composition, from which a cured film having a low dielectric constant can be obtained and which is excellent in providing embedding planarity at the time of film formation. A curable composition comprising a fluorinated polyarylene prepolymer (A) having a crosslinkable functional group, and a compound (B) having a molecular weight of from 140 to 5,000, having a crosslinkable functional group and having no fluorine atoms.
