PROBLEM TO BE SOLVED: To provide the manufacturing method of a composite particle capable of preparing an electrochemical element electrode that gives an electrochemical element of highly dense electrode, small internal resistance, and high capacity. SOLUTION: An electrode active substance, a conductive material, a dispersion binding agent and a soluble resin are dispersed or dissolved in a solvent to obtain slurry configured by dispersing the electrode active substance, conductive material and dispersion binding agent, and dissolving the soluble resin; and the composite particle is obtained by spray drying the slurry to prepare granulation. The composite particle is sheeted by roll pressure forming process or the like to obtain the electrochemical element electrode by laminating the sheets on a collector. COPYRIGHT: (C)2007,JPO&INPIT
