Abstract
According to one embodiment, an electrode structure is provided. The electrode structure includes a current collector, an active material layer provided on at least one surface of the current collector, and a separator layer provided on the active material layer. The separator layer includes a first region, and a second region which is adjacent to the first region and exists in the inside of the first region. An outline of a principal surface of the active material layer overlaps the first region of the separator layer, and a thickness of at least a part of the first region is thicker than a thickness of the second region.
