The transition metal oxide containing solid-solution lithium is represented by the compositional formula: Li 1.5 [Ni a M b Mn c [Li] d ]O 3 (in the formula, Li represents lithium, Ni represents nickel, M represents at least one kind of element selected from the group consisting of silicon, phosphorus and metal elements (but excluding Ni, Mn and Li), Mn represents manganese, and O represents oxygen, and a, b, c and d satisfy the relationships of 0 < a < 1.4, 0 < b ¤ 0.2, 0 < c < 1.4, 0.1 < d ¤ 0.4, a + b + c + d = 1.5 and 1.1 ¤ [a + b + c] < 1.4, and n, which is the valence of M, is in a range of 3 ¤ n ¤ 6 (when M consists of two or more elements, n is the average value of the valence of each element)). The oxide has a layered structure site and a site which changes to a spinel structure by performing a charge or a charge-discharge in a predetermined electric potential range, and a spinel structure change ratio k of the transition metal oxide containing solid-solution lithium is in a range of 0.25 ¤ k < 1.0 when the spinel structure change ratio is assumed to be 1 in a case where Li 2 MnO 3 of the layered structure in the transition metal oxide containing solid-solution lithium completely changes to LiMn 2 O 4 of the spinel structure.",
