PURPOSE: To provide a negative electrode material used for lithium secondary battery, a method for manufacturing it, and a lithium secondary battery using it. CONSTITUTION: A negative electrode material contains at least carbon atom and one kind or more of metals, the metal consists of an element of the VIA, VIII, IB or IVB groups of the periodic table, and its content is 0.01-40wt.%. The carbon atom consists of the burned product of a carbonizable or graphitizable resin or organic material, or carbon or graphite, a mixture of the carbonizable or graphitizable resin or organic material or the burned product of the carbonizable or graphitizable resin or organic material with a compound of the metal, or a mixture of carbon or graphite with the compound of the metal is burned at 600-3000 deg.C in non-acidifying atmosphere. A lithium secondary battery using this negative electrode material as battery constituting element is provided. |
