Abstract

A binder composition for a non-aqueous secondary battery electrode contains a specific binder component, a plasticizer, and an organic solvent. The binder component includes an insoluble polymer that includes a (meth)acrylic acid ester monomer unit and an ethylenically unsaturated acid monomer unit and a highly soluble polymer that includes, in specific content ratios, a nitrile group-containing monomer unit and either or both of an amide group-containing monomer unit and a (meth)acrylic acid ester monomer unit having an alkyl chain carbon number of not less than 1 and not more than 6.
