The present invention provides an electrode material for a lithium ion secondary battery capable of realizing a lithium ion secondary battery capable of maintaining high-current charge and discharge for a long period of time during its lifetime and having a high capacity, a method for producing the same, and a lithium ion secondary battery. In an electrode material for a lithium ion secondary battery containing an active material and a conductive material, the active material is set to lithium-containing composite oxide, tin oxide, or silicon oxide, and amorphous carbon, carbon nanotubes, and In carbon black, part or all of the surface of the active material is covered with amorphous carbon. |
