A negative electrode material for a non-aqueous electrolyte secondary battery includes a plurality of composite particles. Each of the plurality of composite particles includes an inorganic particle and a carbonaceous material layer that covers the inorganic particle. The carbonaceous material layer includes a first region having a porosity of 4.7% or more and 34.8% or less, the first region beinga region extending from the surface of the inorganic particle to the surface of an imaginary sphere that is centered at the center of the inorganic particle and has a radius of 3r, where r is a radius of the inorganic particle.
