It is an object of the present invention to quickly dissipate the heat generated when a short circuit occurs between the anode and cathode. An encapsulating medium made of a laminated film and containing a unit cell is introduced, and the laminated film of the encapsulant includes a metal material having a thermal conductivity k of at least 230 Wm −1 K −1 at room temperature. A nonaqueous-electrolyte cell is disclosed. Furthermore, the ratio R of the volume of the metal material portion of the encapsulant to the unit cell capacity of 1 mAh is 0.0002 cm 3 / mAh ≤ R ≤ 0.003 cm 3 / mAh.n n n n Non-aqueous electrolyte cell, unit cell, encapsulant, current collector, metal material |
