The present disclosure relates to a binder for nonaqueous electrolyte secondary battery electrodes. The present disclosure is a binder for nonaqueous electrolyte secondary battery electrodes, which contains an acrylic crosslinked polymer or salt thereof, and which is characterized in that: the acrylic crosslinked polymer contains, in all the constituent monomers thereof, 30-90% by weight of an ethylenically unsaturated carboxylic acid monomer (component (a)) and 10-70% by weight of an ethylenically unsaturated monomer containing no carboxyl group and having an SP value of a homopolymer of 9.0-12.5 (cal/cm3)1/2 (component (b)); and the ratio of monomers having an acryloyl group in all the constituent monomers is 70% by weight or more. |
