Provide is a polymer that can provide excellent toughness and weather resistance to a rubber composition and a rubber product such as a tire. The multicomponent copolymer contains a conjugated diene unit, a non-conjugated olefin unit and an aromatic vinyl unit, where a proportion of conjugated diene units bonded to a unit other than a conjugated diene unit out of the total conjugated diene units is 50% or more.
