Abstract
The present invention provides an electrode mixture layer for nonaqueous electrolyte secondary batteries, which contains an electrode active material, a carbon-based conductive agent containing fibrous carbon having an average effective length of 10 μm, and a binder, and which has a thickness of 50 μm or more. This electrode mixture layer has an inner layer portion where the fibrous carbon is three-dimensionally dispersed in a random manner.
