Abstract
An electrode is provided with a conductive intermediate layer that is arranged between a core material and a mixture layer. The mixture layer contains an active material and a first binder; and the intermediate layer contains a conductive material and a second binder. The conductive material has a particle size distribution which has a first peak that is within the particle diameter range from 0.005 μm to 0.07 μm and a second peak that is within the particle diameter range from 0.5 μm to 10 μm. The content of the particles that constitute the first peak is 1% by mass to 40% by mass of the mass of the conductive material. The second binder is mainly composed of a thermoplastic resin that has a melting point of 100° C. to 200° C., and has a composition that is different from the composition of the first binder.
