摘要：
A composition for an electrode of a nonaqueous electrolyte secondary battery contains an active material and a binder resin. The composition contains a vinylpyrrolidone-based polymer as the binder resin. The hydroxyl group equivalent of the vinylpyrrolidone-based polymer is within the range of 250 to 2500.
