Abstract
According to one embodiment, an active material is provided. The active material includes a first phase including a niobium-titanium composite oxide, and a second phase adjacent to the first phase and including an orthorhombic niobium oxide. The active material is a particle in which a second (010) plane of the orthorhombic niobium oxide is in contact with a first (010) plane of the niobium-titanium composite oxide in at least a part of a contact interface between the first phase and the second phase.
