According to one embodiment, an electrode is provided. The electrode includes the active material-containing layer formed on the current collector and including active material particles. The particle size distribution chart obtained by the laser diffraction scattering method for the active material particles includes the first region and the second region. The first particle group included in the first region includes the first active material particles, and the second particle group included in the second region includes second active material particles. The carbon coverage of the first particle group is higher than the carbon coverage of the second particle group.
