Zusammenfassung:To provide a curable resin composition, from which a cured product having high heat resistance, a low dielectric loss tangent, high adhesion to a conductor can be obtained. A dry film, a resin-clad copper foil, a cured product, and an electronic component containing the curable resin composition are to be provided. A curable resin composition containing (A) an epoxy resin and (B) a compound having an active ester group is obtained, which has ratio of the total amount of epoxy group(s) in (A) the epoxy resin/the total amount of active ester group(s) in (B) the compound having an active ester group in the composition in the range of 0.2 to 0.6. A dry film, a resin-clad copper foil, a cured product, and an electronic component containing the curable resin composition are also obtained.
