In general, according to one embodiment, an electrode is provided. The electrode includes an active material and a titanium-containing solid electrolyte. The active material includes a transition metal oxide. In an X-ray absorption fine structure spectrum of Ti—K absorption edge for the electrode in a discharged state, a first X-ray absorption amount I at a first incident X-ray energy satisfies 0.2≤I≤0.6. In an X-ray absorption fine structure spectrum of Ti—K absorption edge for anatase titanium dioxide, a second X-ray absorption amount at a second incident X-ray energy is equal to the first X-ray absorption amount I. The first incident X-ray energy is higher than the second incident X-ray energy.
