Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lithium titanium oxide whose particle is especially small and electrochemical characteristic is improved, a method for producing especially lithium titanate Li4Ti5O12, and an electrode which contains a carbon-containing lithium titanium oxide as an active material, and a lithium ion secondary battery containing this electrode.SOLUTION: The capacitance characteristic is improved, by including a step (a) which mixes lithium salt, titanium oxide and a carbon-containing compound in a solvent, a step (b) which dries the mixture obtained at the step (a), and a step which calcinates the dried mixture.
