Abstract

An electricity-storing device electrode includes a current collector foil, an active material layer formed on a surface of the current collector foil, and a high-resistance layer formed on the surface of the current collector foil so as to be adjacent to and in direct contact with the active material layer. At at least a portion of the interface between the active material layer and the high-resistance layer, mixed phase is formed where constituents from the two layers intermingle.
