PROBLEM TO BE SOLVED: To provide a composite electrode material having composite oxide particles, a method of manufacturing a composite electrode material, and a composite electrode.SOLUTION: A method for manufacturing a composite electrode material comprises bringing an organic precursor of a carbonaceous material into contact with composite oxide particles, thermally decomposing the precursor to obtain an electrode active material comprising nano-sized composite oxide particles coated with carbon, co-pulverizing and mixing the electrode active material and fibrous carbon, and lowering the viscosity of the co-pulverized mixture by adding a binder to the co-pulverized mixture.SELECTED DRAWING: Figure 1 【課題】複合酸化物粒子を有する複合電極材、ならびに複合電極材の製造方法、複合電極の提供。【解決手段】複合酸化物粒子に炭素質材料の有機前駆体を接触させ、該前駆体を熱分解させて炭素被覆されたナノサイズの複合酸化物粒子からなる電極活物質を得、該電極活物質と繊維状炭素とを共粉砕混合し、該共粉砕混合物にバインダーを添加することによって該共粉砕混合物の粘度を低下させることを含む、複合電極材の製造方法。【選択図】図１
