PROBLEM TO BE SOLVED: To provide a new improved manufacturing method of a narrow molecular weight distributed hydroxystyrene-type polymer. SOLUTION: A hydroxystyrene monomer shown in general formula (2) (where, R<SB>1</SB>is an alkyl group, an alkylcarbonyl group, an alkoxycarbonyl group, an alkylsilyl group, an aryl group, an aryllalkyl group or an alkoxyalkyl group) is polymerized by using a compound shown in general formula (1) (where, X is halogen atom) and a metal halide having a Lewis acid as an initiator.
