The present invention pertains to an electrode material, an electrode, and a capacitor device. The electrode material contains solid phase A comprising a metal, metalloid, or oxide thereof, having lithium occluding capability, and a solid phase B comprising a metal, metalloid, or oxide thereof, having lithium occluding capability lower than that of the material forming the solid phase A. The ratio L B ／L A of the crystallite size L B of the solid phase B and the crystallite size L A of the solid phase A, calculated from the first peak in the X-ray diffraction spectrum of the material forming each phase, is 1.00 or above. |
