Disclosed is a method for producing a lithium-containing composite oxide that can be fired at a lower temperature and can improve conductivity without reducing crystallinity. A method for producing a lithium-containing composite oxide represented by the following general formula (1): a step of preparing a solution by dissolving a raw material in a solvent; and conductive carbon particles in the obtained solution A step of adding, a step of gelling the obtained solution, and a step of firing the obtained gel. During Li x M y P 1-z X z O 4 (1) ( wherein, M is at least one element selected Fe, Ni, Mn, Zr, Sn, from the group consisting of Al and Y, X is at least one selected from the group consisting of Si and Al, and is in the range of 0 <x ≦ 2, 0.8 ≦ y ≦ 1.2, and 0 ≦ z ≦ 1.)
