Abstract

A curable composition includes an olefin-aromatic vinyl compound-aromatic polyene copolymer satisfying conditions (1) to (4) and an additive resin, which is at least one of a hydrocarbon-based elastomer, polyphenylene ether, olefin-aromatic vinyl compound-aromatic polyene copolymerized oligomer, and aromatic polyene-based resin. (1) The number average molecular weight of the copolymer is 5000 to 100000. (2) The aromatic vinyl compound monomer has 8 to 20 carbon atoms, and the content of the unit of the monomer is 0 to 70 mass %. (3) The aromatic polyene is selected from polyenes having 5 to 20 carbon atoms and a plurality of vinyl and/or vinylene groups in the molecule, and the content of the groups is 1.5 to 20 pieces per number average molecular weight. (4) The olefin is selected from olefins having 2 to 20 carbon atoms, and the total monomer units of the olefin, aromatic vinyl compound, and aromatic polyene is 100 mass %.
