PROBLEM TO BE SOLVED: To provide a fiber sizing agent that is excellent in sizing capability.SOLUTION: Provided is a fiber sizing agent containing a copolymer that comprises at least one section (A) obtained by polymerizing a monomer (a) that contains vinyl pyrrolidone, and at least one section (B) obtained by polymerizing a monomer (b) that contains ethylenically unsaturated monomer other than vinyl pyrrolidone, and that is formed by a living radical polymerization process including a step for forming the section (A), and a step for forming the section (B). 【課題】集束性に優れる繊維集束剤を提供する。【解決手段】ビニルピロリドンを含有する単量体（ａ）を重合してなるセクション（Ａ）と、ビニルピロリドン以外のエチレン性不飽和単量体を含有する単量体（ｂ）を重合してなるセクション（Ｂ）とを少なくとも一つずつ有し、上記セクション（Ａ）を形成する工程とセクション（Ｂ）を形成する工程とを有するリビングラジカル重合法により形成された共重合体を含有する繊維集束剤を用いる。【選択図】なし
