A method for producing a conjugated diene-based polymer is described. The conjugated diene-based polymer is produced by polymerizing monomers including a conjugated diene compound, a compound represented by the following formula (1) and a compound represented by the following formula (2) using an organoalkali metal compound and a secondary amine compound, and then reacting a compound containing a nitrogen atom and/or a silicon atom to an active end of the polymer formed via the polymerization,
