An electrode material including electrode active material particles and a carbonaceous film layer coating surfaces of the electrode active material particles and including a metal oxide, a content ratio of the metal oxide in the carbonaceous film layer being 5% by mass to 70% by mass. A method for manufacturing an electrode material, in which electrode active material particles, a metal salt or metal alkoxide containing any one or more metal atoms selected from a group consisting of Al, Zr, Si, and Ti, and an organic compound which is a precursor of carbon are mixed so that a total blending amount of the metal salt or metal alkoxide satisfies that an amount of a metal oxide in the carbonaceous film layer when the metal salt or metal alkoxide is all changed to the metal oxide is 5% by mass to 70% by mass, and are heated in a non-oxidative atmosphere. |
