The present invention provides a conjugated diene based rubber comprising a conjugated diene based copolymer comprising at least two conjugated diene monomer units and optionally comprising a vinyl aromatic hydrocarbon monomer unit, wherein the conjugated diene based copolymer comprises a first block composed of a first conjugated diene monomer unit and the vinyl aromatic hydrocarbon monomer unit or a second conjugated diene monomer unit, the second conjugated diene monomer unit being distinct from the first conjugated diene monomer unit, the first block being random; and a second block, comprising at least the second conjugated diene monomer unit and optionally comprising the vinyl aromatic hydrocarbon monomer unit, wherein the first block is connected to the second block, and the amount of the vinyl aromatic hydrocarbon monomer units or the second conjugated diene monomer units is at least 35 wt % of the first block.
