NOVELTY - The nonaqueous electrolyte battery has a case (2) which includes a housing section housing the electrode group. A sealed section is formed in a peripheral section of the case. A lead-sandwiching section is positioned between the housing and sealed sections. The lead-sandwiching section, having a first zone (21B1) and a second zone (21B2), sandwiches the electrode lead between the first and second zones. The first and second zones of the lead-sandwiching section include the opening sections (21Ca,21Cb), and at least a section of the electrode lead is exposed through the opening section.    USE - Nonaqueous electrolyte battery for use as power source for mobile devices e.g., mobile phone. Uses include but are not limited to notebook computer, smart phone, electric vehicle, electric assistant bicycle, and uninterruptible power supply.    ADVANTAGE - Prevents the penetration of the moisture through the lead-sandwiching section by preventing the moisture contained in the external air from reaching the electrode group. Prevents leakage of the nonaqueous electrolyte to the exterior of the battery from the interior section of the battery since the nonaqueous electrolyte battery includes an electrode lead that heat-sealed to the periphery of the opening section formed in the lead-sandwiching section exhibits a good sealing property. Increases the battery capacity since the strength of the negative electrode current collector can be drastically increased and the density of the negative electrode can be increased under high press pressure. Improves charge-and-discharge cycle characteristics of the battery.
