This invention relates to a non-aqueous electrolyte cell having an improved utilization of manganese dioxide. The utilization of manganese dioxide of a conventional non-aqueous electrolyte cell comprising a negative active material which comprises lithium, sodium or the like; a positive active material which comprises manganese dioxide; and a non-aqueous electrolyte can be greatly improved by limiting the particle sizes of manganese dioxide powder, carbon powder and optional binder powder contained in the positive mass to, respectively, up to 30 mmm
