Zusammenfassung:Provided are: a rubber composition capable of giving rubber parts that have improved adhesiveness; a rubber composite which includes a portion where rubber parts have been bonded to each other at improved adhesive force; and a rubber crawler which includes a portion where rubber parts have been bonded to each other at improved adhesive force. The rubber composition according to the present invention includes at least a polymer component, wherein the polymer component comprises a styrene/butadiene rubber ingredient that is either a styrene/butadiene rubber alone or a mixture of a styrene/butadiene rubber and a butadiene rubber, the styrene/butadiene rubber ingredient having a styrene content less than 20 mass% and the styrene/butadiene rubber being an oil-extended styrene/butadiene rubber.Alternatively, the polymer component in the rubber composition according to the present invention contains a styrene/butadiene rubber ingredient in an amount smaller than 50 parts by mass per 100 parts by mass of the polymer
