摘要： Disclosed is a positive electrode material having improved charging/discharging cycle characteristic, shelf stability, and discharge load characteristic, and a secondary battery using the material. A rolled electrode body obtained by rolling strip-shaped positive and negative electrodes with a separator inbetween is provided on the inside of a battery can. The separator is impregnated with an electrolytic solution. The positive electrode contains a positive electrode material in which a coating portion is provided on the surface of a center portion made of a lithium composite oxide such as LiMn2O4. The coating portion is made of a conductive oxide such as ITO (indium tin oxide) or SnO2. The quantity of the coating portion is 0.001 mol to 0.1 mol per 1 mol of the center portion. By the technique, while assuring conductivity, elution of the positive electrode material into the electrolytic solution can be suppressed and a reaction product can be prevented from being deposited on the surface of the positive electrode.
