Disclosed is a binder composition for a non-aqueous secondary battery electrode, which enables the production of a non-aqueous secondary battery that has excellent adhesion to a current collector or an electrode and can retain a high electric discharge capacity even when charge and discharge are repeated or under a high-temperature environment produced as a result of the generation of heat. Specifically disclosed is a binder composition for a non-aqueous secondary battery electrode, which comprises functional group-containing crosslinked resin microparticles produced by polymerizing the following components (A) to (C): (A) at least one monomer selected from the group consisting of (a) a monomer having one ethylenically unsaturated group per molecule and also having a monofunctional or polyfunctional epoxy group, (b) a monomer having one ethylenically unsaturated group per molecule and also having a monofunctional or polyfunctional amide group, and (c) a monomer having one ethylenically unsaturated group per molecule and also having a monofunctional or polyfunctional hydroxy group; (B) at least one monomer selected from the group consisting of (d) a monomer having one ethylenically unsaturated group per molecule and also having an alkoxysilyl group and (e) a monomer having at least two ethylenically unsaturated groups per molecule; and (C) (k) a monomer which has an ethylenically unsaturated group and is different from the monomers (a) to (e).
