An object of the present invention is to provide a multicomponent copolymer for use for producing a rubber composition and a rubber product such as tires and the like excellent in crack resistance and further having low heat generation while maintaining high weather resistance. Further, the present invention is to provide a rubber composition containing the multicomponent copolymer, a crosslinked rubber composition obtained by crosslinking the rubber composition, and a rubber product and a tire using the rubber composition or the crosslinked rubber composition. The multicomponent copolymer of the present invention contains a conjugated diene unit, a non-conjugated olefin unit and an aromatic vinyl unit, wherein the main chain is formed of an acyclic structure alone and the content of the aromatic vinyl unit is 5 mol % or less of the whole multicomponent copolymer.
