description Provided is a positive electrode for a non-aqueous electrolyte secondary battery, which can suppress a decrease in initial charging capacity even when using a positive electrode that is exposed to air. One embodiment of this positive electrode for a non-aqueous electrolyte secondary battery is a positive electrode for a non-aqueous electrolyte secondary battery that contains a lithium-containing transition metal complex oxide represented by the general formula Li1+xMnaMbO2+c (in the formula, x, a, b and c satisfy the conditions x+a+b=1, x is greater than 0 and smaller than or equal to 0.2, a is greater than or equal to 0.09, and c is greater than 0 or equal to -0.1 and smaller than or equal to 0.1, and M is at least one type of element selected from among the group consisting of transition metal elements other than Mn, alkali metal elements, alkaline earth metal elements, and elements of groups 12, 13 and 14), wherein the positive electrode for a non-aqueous electrolyte secondary battery contains tungsten oxi
