According to one embodiment, an electrode is provided. The electrode includes a current collector and an active material-containing layer formed on the current collector and containing active material particles. A median diameter (D50) calculated from a volume-based frequency distribution chart obtained by a laser diffraction/scattering method for the active material particles is in the range of 1.2 μm to 4.0 μm. In the frequency distribution chart, a proportion of an integrated amount of particles having a particle size of 2.0 μm or less is in the range of 36% to 62% with respect to the entire active material particles on a volume basis.
