Abstract: This binder for battery electrodes is characterized by containing a polymer including: (A) a structural unit represented by general formula (1) and derived from a monomer having a hydroxyl group (in the formula, R1 is a hydrogen or a C1-C4 straight-chain or branched alkyl group, R2 and R3 are each a hydrogen or a C1-C4 straight-chained or branched alkyl group, and n is an integer of 2-30); (B) a structural unit derived from an ethylenically unsaturated monomer having at least one functional group selected from the group consisting of a difunctional carboxylic acid group, a nitrile group and a ketone group; and (C) a structural unit derived from a polyfunctional (meth)acrylate monomer having at most five functional groups.
