Claim Text:
1. A conjugated diene polymer comprising at least a conjugated diene monomer unit; wherein the polymer has at least one group as a terminal group of a polymer chain selected from the group consisting of a group represented by formula (1), a group represented by formula (2), and a group represented by formula (3),  wherein in formula (1) X represents a chlorine atom, a bromine atom or an iodine atom; and R  wherein in formula (2) X represents a chlorine atom, a bromine atom or an iodine atom; and R  wherein in formula (3) X represents a chlorine atom, a bromine atom or an iodine atom; R  wherein in formula (4) Y  wherein in formula (5) Y wherein the conjugated diene polymer has a number-average molecular weight (Mn) in terms of polystyrene of 1,000 to 1,000,000, a ratio (Mw/Mn) of a weight-average molecular weight (Mw) to the number-average molecular weight (Mn) of lower than 2.0 and the conjugated diene polymer bears a halogen atom at a terminal of the polymer chain.
