BINDER COMPOSITION FOR ELECTROCHEMICAL DEVICE, CONDUCTIVE MATERIAL DISPERSION LIQUID FOR ELECTROCHEMICAL DEVICE, SLURRY COMPOSITION FOR ELECTROCHEMICAL DEVICE ELECTRODE, ELECTRODE FOR ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL DEVICE

Provided is a binder composition for an electrochemical device that can stably disperse a conductive carbon material and that can cause an electrochemical device to display excellent output characteristics and high-voltage cycle characteristics. The binder composition for an electrochemical device contains a polymer including a nitrile group-containing monomer unit and an alkylene structural unit and a group 13 element and satisfies a relationship formula: 0.1 ≤ M/I ≤ 150 (in the formula, I is the iodine value [g/100 g] of the polymer and M is the concentration [ppm] of the group 13 element).
