<p>Provided is a nonaqueous electrolyte battery whereby an electrode assembly can be reliably surrounded by a cover member and the displacement of a pole plate in the electrode assembly and the entire electrode assembly can be prevented. A cover member (5) is configured with a bottom face component (51) covering an opposite area (37) opposite a tab arrangement area (35) of an electrode assembly (3), a pair of side face components (53) located between the tab arrangement area (35) and the opposite area (37), covering a pair of side face areas (38) facing the laminate direction of the electrode assembly (3), and a pair of end face components (55) located between the tab arrangement area (35) and the opposite area (37), covering a pair of end face areas (39) facing a direction orthogonal to the laminate direction of the electrode assembly (3). A pair of coupling pieces (52, 54) constituting at least a part of a coupling structure portion (57) for coupling the pair of side face components (53) above the tab arrangement area (35) is provided on an edge portion (53b) opposite an edge portion (53a) where the pair of side face components (53) is connected to the bottom face component (51).</p> |
