    • Provided is a composition from which a cured material having excellent low dielectric properties and high adhesiveness to a metal foil may be obtained and a laminate including the same. The laminate comprising an olefin-aromatic vinyl compound-aromatic polyene copolymer satisfying the following conditions (1) to (4) and a metal foil.
      (1) The number average molecular weight of the copolymer is 5000 or more and 100000 or less. (2) The aromatic vinyl compound monomer is aromatic vinyl compound having 8 or more and 20 or less carbon atoms, and the content of the unit of the aromatic vinyl compound monomer is 10 mass% or more and less than 60 mass%. (3) The aromatic polyene is selected from polyenes having 5 or more and 20 or less carbon atoms and having a plurality of vinyl groups and/or vinylene groups in the molecule, and the content of the vinyl groups and/or the vinylene groups derived from the unit of the aromatic polyene is 1.5 pieces or more and less than 20 pieces per number average molecular weight. (4) The olefin is selected from olefins having 2 or more and 20 or less carbon atoms, being ethylene alone, or having a mass ratio of α-olefin monomer components other than ethylene to an ethylene monomer component contained in the olefin, of 1/7 or less, and the total monomer units of the olefin, aromatic vinyl compound, and aromatic polyene is 100 mass%.
