Abstract
According to one embodiment, an electrode is provided. The electrode includes a current collector and an active material-containing layer. The active material-containing layer is provided on the current collector. The active material-containing layer includes active material particles and insulator particles. The active material-containing layer has a first surface facing the current collector and a second face as a surface of the active material-containing layer. The second face includes a surface of a part of the insulator particles. A volume ratio of the insulator particles decreases from the second face toward the first surface in the active material-containing layer.
