The positive electrode active material is not present in the uncoated portion of the positive electrode current collector. The nonwoven fabric covers an entirety of the coated portion and extends from the outer peripheral portion of the coated portion to form a surplus region, and the surplus region is sealed so as to close all around the outer peripheral portion of the coated portion.
