PROBLEM TO BE SOLVED: To provide a bonding agent that is excellent in bonding properties and electrolyte resistance, an electrode manufactured using this bonding agent, and a nonaqueous electrolyte battery that is excellent in charge/discharge characteristics utilizing the same.SOLUTION: A copolymer has at least one section (A) obtained by polymerizing a monomer (a) containing vinylpyrrolidone and at least one section (B) obtained by polymerizing a monomer (b) containing an ethylenic unsaturated monomer other than vinylpyrrolidone. A bonding agent for an electrode is used containing a copolymer formed by a living radical polymerization method having a step for forming the section (A) and a step for forming the section (B). 【課題】結着性及び耐電解液性に優れた結着剤、この結着剤を用いて製造された電極、及びこれを使用した充放電特性に優れた非水電解質電池を提供する。【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電極用結着剤を用いる。【選択図】なし
