Zusammenfassung:	To provide a dispersant for carbon black that can reduce residual components after firing, derived from the dispersant for carbon black, which affects the conductivity when used in an electrode, and a carbon black dispersion including the dispersant and an electrode material including the carbon black dispersion.SOLUTION: A dispersant for carbon black contains a copolymer having at least one (meth)acrylate selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate and 2-hydroxyethyl (meth)acrylate, and 2-(meth)acrylamide-2-methylpropanesulfonic acid (salt) as essential constituent monomers.SELECTED DRAWING: None 【課題】電極にしたとき導電性に悪影響を与えるカーボンブラック用分散剤に由来する焼成後の残留成分を低減できるカーボンブラック用分散剤、それを用いたカーボンブラック分散液及び前記カーボンブラック分散液を含む電極用材料を提供することを目的とする。【解決手段】（メタ）アクリル酸メチル、（メタ）アクリル酸エチル及び（メタ）アクリル酸－２－ヒドロキシエチルからなる群から選ばれる少なくとも１種類の（メタ）アクリル酸エステルと、２－（メタ）アクリルアミド－２－メチルプロパンスルホン酸（塩）とを必須構成単量体とする共重合体を含むカーボンブラック用分散剤を用いる。【選択図】なし
