To provide a positive electrode in which high discharging capacity and an excellent cycle characteristic are displayed and electric conductivity is given by uniformly dispersing conductive auxiliary material in the positive electrode material, and provide a method by which such positive electrode material is easily manufactured.

Positive electrode material is composed of lithium transition metal composite oxide of 70 to 90 percentage by weight and carbon of 30 to 10 percentage by weight. The carbon of 30 to 10 percentage by weight which is formed by carbonizing an organic compound is uniformly dispersed in the matrix of the lithium transition metal composite oxide of 70 to 90 percentage by weight. The manufacturing method is to temporarily burn the mixture of a transition metal compound and a lithium compound so as to obtain a temporarily burnt substance, and to mix the temporarily burnt substance into dispersion solution which is formed by dispersing the organic compound into solvent, and to regularly burn the mixture.
