Abstract

A binder resin for a nonaqueous secondary battery electrode of the invention satisfies Is≧30 (Is indicates a sum of scattering intensities observed in a particle size range of from 1 to 100 nm) when a solution is formed by dissolving the binder resin in water at a concentration of 5% by mass and particle size distribution is measured by a dynamic light scattering method at 25° C. The binder resin contains a polymer (B) having a structural unit represented by the following Formula (11) and a specific structural unit. The binder resin also contains a polymer (α) having a specific structural unit and a structural unit represented by the following Formula (22), and/or a mixture of a polymer (β1) having a specific structural unit and a polymer (β2) having a structural unit represented by the following Formula (22).
