摘要： PROBLEM TO BE SOLVED: To provide an electrode where an internal resistance is reduced while maintaining an energy density.SOLUTION: Projections and depressions are formed for an active material layer 12 to thereby obtain different thicknesses of the active material layer 12 with respect to a current collection layer 11 for the projections and the depressions. Therefore, in parts 33 where the depressions are formed and a distance to the current collection layer 11 is short, an electrical internal resistance decreases. Also, the projections and depressions of the active material layer 12 is formed through application of a force to the active material layer 12. Consequently, there is no change in total amount of active material particles contained in the active material layer 12. As a result, when the projections and depressions are formed for the active material layer 12, there occurs no change in energy density of the active material layer 12 between before the formation of the projections and depressions and after the formation.
