Abstract
A negative electrode active material is composed of a silicon material coated with a carbon layer containing a Group 4 to 6 metal. A method for producing a negative electrode active material includes a step of decomposing a compound containing the Group 4 to 6 metal and a carbon source by heating in the presence of a silicon material, the compound, and the carbon source.
