  "textContent": "According to one embodiment, a battery is provided. The battery includes an external container, an electrode group, and a sealing plate. The external container includes a bottom wall and a lateral wall. The lateral wall extends from the bottom wall in a first direction. The external container is provided with an opening portion opposing the bottom wall. The electrode group includes a positive electrode, a negative electrode, and an insulating layer. The positive electrode and the negative electrode are wound in a flat shape with the insulating layer interposed therebetween. The electrode group is housed in the external container such that a winding axis direction is orthogonal to the first direction. The sealing plate is attached to the opening portion of the external container. A thickness of the positive electrode and a thickness of the negative electrode are equal to or different from each other. A thickness T of each electrode is from 0.03 mm to 0.08 mm. A second direction is a direction parallel to the winding axis direction. A third direction is a direction orthogonal to the first direction and the second direction. The thickness T (mm) of the electrode, a thickness T (mm) of the electrode group in a direction parallel to the third direction, and an innermost circumferential height H (mm) of the electrode group in a direction parallel to the first direction satisfy following formula (1): 0.02 ≤ T E × T W / H IC ≤ 0.04",
