A non-aqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The negative electrode includes a molded body made by compression molding a granulated material containing a negative electrode active material, a conductive agent, and a binder. The negative electrode active material includes a Si-containing material. Volume-based 90% particle size R (D90) of the negative electrode active material, volume-based 10% particle size Rz (D10) and 90% particle size Rz (D90) of the granulated material, and thickness T of the molded body satisfy the following relation formulae: (i) R (D90)<Rz (D10), (ii) Rz (D90)<T, (iii) 34μm≰Rz (D10)≰126μm, and (iv) 128μm≰Rz (D90)≰285μm, and the electric conductivity of the granulated material is 0.05 S/cm or more when the density of the granulated material is 0.9 g/cm3.
