Abstract
According to one embodiment, there is provided a laminate including a first current collector, a first current collector tab, a first active material-containing layer, and a first film containing an inorganic material. A back surface of the first active material-containing layer is supported on at least a part among front and back surfaces of the first current collector. A first thickness at a first end surface of the first active material-containing layer is smaller than a second thickness at a second end surface facing reverse with respect to the first end surface. The first film covers at least the first end surface of the first active material-containing layer and a portion among front and back surfaces of the first current collector tab adjacent to the first end surface.
