Abstract

According to one embodiment, an electrode is provided. The electrode includes a current collector, and an active material-containing layer which is formed on a surface of the current collector and includes a plurality of niobium titanium composite oxide particles. A X-ray diffraction pattern using a Cu-Kα ray source with respect to a surface of the active material-containing layer includes a peak A with a highest intensity in a range of 2θ=26°±0.2° and a peak B with a highest intensity in a range of 2θ=23.9°±0.2°. An intensity ratio (Ia/Ib) between an intensity Ia of the peak A and an intensity Ib of the peak B is in a range of 1.80 or more to 2.60 or less.
