Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for the industrial production of an elastomer composition usable as a base polymer of an adhesive exhibiting initial tackiness at low temperature and adhesive force at high temperature and having excellent processability. SOLUTION: A conjugated diene polymer (B) is newly produced by adding a polymerization initiator and a conjugated diene monomer to a solution containing a block copolymer (A) having a [terminal polyaromatic vinyl block- poly(conjugated diene) block] structure and containing ≥2 terminal polyaromatic vinyl blocks and polymerizing the monomer.
