Abstract
An electrode body includes a substrate serving as a collector, a mixture layer formed on the substrate and containing an electrode active material, and an insulation layer formed on the substrate adjacent to the mixture layer. The insulation layer contains an insulative material. In an interfacial region of the mixture layer and the insulation layer, the mixture layer extends over and overlaps the insulation layer that covers a surface of the substrate. Further, an interfacial surface of the insulation surface interfacing the mixture layer includes undulations having an undulation width that is greater than a particle size of the electrode active material.
