Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new material which can hold an average discharge voltage of ≥3 V and can have a discharge capacity equal to or above that of a lithium-cobalt oxide based positive electrode material in a charge-discharge cycle over a long period, and which can be obtained using inexpensive raw material having little restraint in resources and further can exhibit more excellent charge-discharge properties compared with well-known inexpensive positive materials. SOLUTION: The lithium ferritic compound oxide is expressed by the compositional formula of Li1+x(Mn1-m-nFemAln)1-xO2(0
