The method of making a composite particle for an electrode in accordance with the present invention comprises a granulating step of integrating a conductive auxiliary agent and a binder adapted to bind the conductive auxiliary agent and an electrode active material together with a particle made of the electrode active material while in close contact with each other in an inert gas atmosphere so as to form a composite particle for an electrode containing the electrode active material, conductive auxiliary agent, and binder. When the composite particle obtained by this method is used as a constituent of an electrode, an electrode having an excellent electrode characteristic and an electrochemical device having excellent electrochemical characteristics can be formed easily and reliably.
