Provided is a conjugated diene polymer containing at least conjugated diene monomer units, wherein the conjugated diene polymer has a molecular weight distribution curve obtained by GPC measurement where three or more peaks are present, and the peak top molecular weight of a finally detected peak (Z) is 80000 to 250000, and a polymer chain corresponding to a maximum peak (L) has a degree of adsorption onto silica of less than 40% where in the molecular weight distribution curve, the last detected peak in the GPC measurement is defined as the finally detected peak (Z), and a peak having the largest peak area among peaks excluding the finally detected peak (Z) is defined as the maximum peak (L).
