Provided is a binder composition for an electrochemical device that has excellent binding capacity and is capable of forming a functional layer that can improve rate characteristics and cycle characteristics of an electrochemical device (for example, a secondary battery). The binder composition for an electrochemical device contains a binder and an organonitrogen compound. The binder is a polymer including at least one functional group selected from the group consisting of a carboxyl group, a hydroxyl group, a cyano group, an amino group, an epoxy group, an oxazoline group, an isocyanate group, and a sulfo group. The organonitrogen compound includes at least one functional group selected from the group consisting of an azo group, a hydrazino group, a hydrazo group, and a nitroso group, has a 5% mass loss temperature of 140 C. or higher, and has a molecular weight of not less than 80 and not more than 1,000.
