Abstract: A positive electrode active material for a secondary battery has a lithium metal composite oxide having a crystal structure based on a rock salt structure belonging to a space group Fm-3m, and the crystal structure has a vacancy to which no lithium or metal atom is disposed. For the lithium metal composite oxide, for example, a composite oxide represented by a composition formula LiaMnbMcO2-dFd (where M is at least one metal element excluding Li and Mn, 0
