NEGATIVE ELECTRODE MATERIAL FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

A negative electrode material for a non-aqueous electrolyte secondary battery includes composite particles, and a conductive layer disposed on a surface of each of the composite particles. The composite particles each have a silicate phase, and silicon phases dispersed in the silicate phase. The conductive layer contains a calcium component.
