A cathode active material is provided by which excellent charge and discharge properties in a high-current range can be obtained when used in non-aqueous electrolyte secondary batteries. The cathode active material consists of a mixed metal fluoride represented by the general formula Fe(1-x)MxF3. M is a metal element selected from the group consisting of Y, Mn, Cu, Zn, and Cr. x is 0.01≦̸x≦̸0.15. |
