PROBLEM TO BE SOLVED: To provide a novel polymerization initiator exhibiting good initiator efficiency or a capping agent corresponding to the kind of monomers or additives in living anionic polymerization. SOLUTION: The manufacturing method of a polymer causes an anion, obtained by causing a compound represented by formula (II) (wherein R<SB>5</SB>is a hydrocarbon optionally bearing a double bond) to react with an organometal, an alkali metal or an anion at the end of an anionic polymerization chain, to serve as a starting point of polymerization.
