Abstract
An electrode for a nonaqueous electrolyte secondary battery that is less likely to cause loss of a mixture layer and that can ensure good cycle characteristics of the battery. An electrode for a nonaqueous electrolyte secondary battery of an exemplary embodiment includes a rectangular current collector and a mixture layer that contains an active material and a binder and that is formed on the current collector. The mixture layer covers at least one edge of four linear peripheral edges of the current collector, and the binder content in the mixture layer has a maximum value at a position 0.5 mm to 5.5 mm away from the one edge in a second direction that is perpendicular to a first direction along the one edge. The maximum value is more than 100% and 240% or less of the binder content at the center in the second direction of the mixture layer.
