Zusammenfassung:An active material includes: a compound A containing elemental Li, an element M, and elemental O, where the element M represents one or more elements selected from elemental Ni, elemental Co, and elemental Mn; and a compound B containing elemental Li, elemental Nb, and elemental O; wherein, in a Raman spectrum obtained by Raman spectroscopy on the active material, the ratio between SPA and SPB, SPB/SPA, satisfies 0 < SPB/SPA ≤ 1.2, where SPA represents the area of a peak assigned to the compound A in a range of 540 to 650 cm-1, and SPB represents the area of a peak assigned to the compound B.
