A non-aqueous electrolyte secondary battery includes: a positive electrode including a positive active material made of a transition-metal-containing complex oxide capable of intercalating lithium ions; a non-aqueous electrolytic solution; and a negative electrode for intercalating and de-intercalating the lithium ions. Provided on the surface of the lithium-containing complex oxide are Li 2 CO 3 , M1 2 CO 3 , and at least one kind of molecules selected from a group represented by R—COOM2. M1 is at least one kind of elements selected from a group consisting of H, Na, and Li. Li 2 CO 3 is excluded from M1 2 CO 3 . R is at least one kind of functional groups selected from a group consisting of alkyl group, alkenyl group, and alkynyl group. M2 is at least one kind of elements selected from a group consisting of H, Na, and Li. |
