According to one approach, an electrode is provided. The electrode includes an active material-containing layer which contains an active material. The active material includes a plurality of primary particles containing a niobium-titanium composite oxide. The average value (FU) of the roughness shape coefficient (FU) according to Formula (1) below is 0.70 or more in 100 primary particles among the plurality of primary particles.[Formula 1]
