PROBLEM TO BE SOLVED : To provide a manufacturing method of an electrode material which uses an element inexpensive and abundant, and provides high discharge capacity, stable charge and discharge cycle performance, high filling property, and high output. SOLUTION : The electrode material is manufactured by adding Li source, A source (provided that, A is one kind or two kinds or more selected from Cr, Mn, Fe, Co, Ni, Cu), D source (provided that, D is one kind or two kinds or more selected from Mg, Ca, Sr, Ba, Ti, Zn, B, Al. Ga, In, Si, Ge, Sc, Y, and rare earth elements), and PO4 source to a solvent having water as a main component to make a solution, and then, by mixing this solution with a dispersion solution prepared by dispersing hydrophilic carbon with oxidized surface in water to make a mixed solution, and then, by spraying and heating this mixed solution.
