Abstract

In general, according to an approach, an electrode (3) includes a current collector (3a) containing aluminum or an aluminum alloy, and an active material-containing layer(3b). The active material-containing layer (3b) contains particles (30) containing a niobium titanium-containing oxide. The electrode satisfies the following expression (1): 0.08≤I1/I2≤0.25 the I1 is an intensity of a first peak having the highest intensity within a range where 2θ is 46° or more and 48° or less in a diffraction diagram obtained by X-ray diffraction on a surface of the active material-containing layer. the I2 is an intensity of a second peak having the highest intensity within a range where 2θ is 25° or more and 27° or less in the diffraction diagram. In a cross section of the active material-containing layer along a thickness direction thereof, an average aspect ratio of the particles is 2 or less.
