PROBLEM TO BE SOLVED: To provide a lithium secondary battery using a lithium transition metal complex oxide as a positive electrode active material, ensuring low internal resistance and a good charge and discharge cycle characteristic. SOLUTION: Two or more kinds of elements selected from Li, Fe, Mn, Ni, Mg, Zn, B, Al, Co, Cr, Si, Ti, Sn, P, V, Sb, Nb, Ta, Mo and W substitute a part of a transition element Me in a lithium-transition element complex oxide LiMeXOY used as a positive electrode active material, where M is a substitution element and M≠Me. |
