The present invention provides a binder composition for electrochemical elements which is excellent in adhesiveness and can form a functional layer which can improve the rate characteristics and cycle characteristics of electrochemical elements (eg, secondary batteries). The binder composition for electrochemical elements of the present invention comprises a binder and a nitrogen-based organic compound, wherein the binder has a group selected from the group consisting of carboxyl group, hydroxyl group, cyano group, amino group, epoxy group, A polymer of at least one functional group selected from an oxazoline group, an isocyanate group and a sulfonic acid group, wherein the nitrogen-based organic compound has at least one selected from the group consisting of an azo group, a hydrazine group, a 1,2-hydrazino group and a nitroso group A functional group, the temperature at which the mass of the nitrogen-based organic compound is reduced by 5% is 140° C. or higher, and the molecular weight is 80 or more and 1000 or less. |
