PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte cell with improved capacity. SOLUTION: The nonaqueous electrolyte cell comprises a positive electrode 14; a negative electrode 17 facing the positive electrode 14; a nonaqueous electrolyte containing layer interposed between the positive electrode 14 and the negative electrode 17; and a case 1 housing the positive electrode 14, the negative electrode 17, and the nonaqueous electrolyte containing layer, to which, a plurality of vent holes 4 for supplying oxygen to the positive electrode 14 are opened. A lithium storing body 19, having a lithium storing layer 20 making the negative electrode 17 store lithium ion by releasing lithium ion at the potential baser than that of the negative electrode 17, is housed in the case 1 so as to fulfill the formula; 0.25P<=R<=0.98Q, where, R represent the distance between the vent holes and the surface of the lithium storing layer, P represents the distance between the inner surface of the case on which the vent holes are formed, and an inner surface of the case facing the above inner surface, or 1/2 of the distance between two surfaces of the case facing each other on which, vent holes are formed, Q represents a shortest distance out of respective distances to the farthest part of the inside surface of the case at respective vent holes. |
