1. A curable composition, comprising:
an olefin-aromatic vinyl compound-aromatic polyene copolymer satisfying the following conditions (1) to (4); and
an additive resin,
wherein the additive resin is one or more selected from the group consisting of a hydrocarbon-based elastomer, an olefin-aromatic vinyl compound-aromatic polyene copolymerized oligomer, and an aromatic polyene-based resin, wherein the hydrocarbon-based elastomer is one or more selected from the group consisting of ethylene-based elastomer, propylene-based elastomer, 1,2-polybutadiene, and hydrides thereof, wherein the 1,2-polybutadiene is liquid at 25° C.:
