Abstract
A secondary battery according to an embodiment includes an exterior material including an opening portion and including a bottom, a wound electrode group housed in the exterior material in order for an insertion direction to be perpendicular to a winding axis, and a lid attached to the opening portion of the exterior material and including at least a plate-like member, a positive electrode terminal, and a negative electrode terminal. When a minimum distance between the lid and the wound electrode group is A, 0.5 mm<A<2.0 mm is satisfied.
