Summary:PROBLEM TO BE SOLVED: To provide a method for highly actively producing a conjugated diene polymer controlled with a new catalyst system. SOLUTION: This method for producing a conjugated diene polymer comprises polymerizing a conjugated diene compound in the presence of a catalyst obtained from (A) the compound of a metal belonging to the group 3 in the periodic table, (B) an ionic compound comprising a non-coordinating anion and a cation, (C) an organic aluminum compound and (D) water [wherein (C):(D)=1:(0.01-2)(molar ratio)].
