Production of a conjugated diene rubber includes polymerizing isoprene or a monomer mixture containing isoprene and an aromatic vinyl monomer in an inert solvent by using a polymerization initiator so as to form a polymer block (A) having an active end, mixing the polymer block (A) having an active end and 1,3-butadiene or a monomer mixture containing 1,3-butadiene and an aromatic vinyl monomer to continue a polymerization reaction so as to obtain a conjugated diene polymer chain having an active end and containing a polymer block (A) and a polymer block (B), and reacting a compound represented by the following general formula (1) with the active end of the conjugated diene polymer chain having an active end: |
