A positive electrode active material (4) and a non-aqueous electrolyte cell (1) which uses the positive electrode active material. The cell has a high discharge voltage without lowering the capacity and superior charging/discharging characteristics. To this end, the positive electrode active material contains a compound represented by the general formula Li x Mn y Fe 1-y PO 4, wherein 0 <x‰ 2 and 0.5 <y< 0.95, or a compound represented by the general formula Li x Mn y A 1-y PO 4 , where 0 < x ‰ 2 and 0 < y < 1 and wherein A is a metal element selected from among Ti, Zn, Mg and Co or plural metal elements selected from among Ti, Fe, Zn, Mg and Co. |
