PURPOSE: Provided is a non-aqueous electrolyte cell employing a cell device obtained on layering and coiling a strip-shaped cathode material and a strip-shaped anode material together to improve the cell device. CONSTITUTION: The non-aqueous electrolyte cell comprises: a cell device including a strip-shaped cathode material and a strip-shaped anode material, which are layered via a separator and coiled a plural number of times; a non-aqueous electrolyte solution; and a cell can for accommodating the cell device and the non-aqueous electrolyte solution, wherein the cathode material employs a cathode active material containing a compound of an olivinic structure represented by a formula LixFe1-yMyPO4, where M is at least one selected from a group consisting of Mn, Cr, Co, Cu, Ni, V, Mo, Ti, Zn, Al, Ga, Mg, B and Nb, with 0.05 <= x <= 1.2 and 0 <= y <= 0.8, which compound is used either singly or in combination with other materials and wherein a ratio of an inner diameter d to an outer diameter D of the cell device is 0.05. |
