BINDER COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY, SLURRY COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY ELECTRODE, ELECTRODE FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY

A binder composition for a non-aqueous secondary battery contains a particulate polymer including a block copolymer A represented by the following general formula (A): Ar1a-Da-Ar2a. (In general formula (A), Ar1a indicates a block region that has a weight-average molecular weight of 5,500 to 20,000 and is formed of an aromatic vinyl monomer unit, Ar2a indicates a block region that has a weight-average molecular weight of 40,000 to 400,000 and is formed of an aromatic vinyl monomer unit, and Da indicates a block region that is formed of an aliphatic conjugated diene monomer unit.)
