The secondary cell—includes an exterior can, a sealing body closing one end of the exterior can, an electrode group disposed inside the exterior can, and an insulating plate disposed between the sealing body and the electrode group. In the electrode group, a positive electrode and a negative electrode are wound in a spiral shape with a separator interposed between. The insulating plate is shaped as a disc having a lead hole penetrated by a positive electrode lead drawn out from the electrode group, and a center hole penetrating the center part of the insulating plate. The outer edge of the lead hole includes a curve part positioned along an arc that is concentric with respect to the outer circumference of the insulating plate as seen in plan view, and linear parts-positioned along a chord linking the two ends of the arc.

Disclosed are a battery, a battery module, a battery pack, and an electric vehicle. The battery includes a housing and at least two electrode core sets connected in series with each other and each including at least one electrode core (4). The electrode core (4) includes a positive plate, a negative plate, and an electrolyte located between the positive plate and the negative plate. The electrolyte is a solid electrolyte or a polymer electrolyte. Isolation layers (43) are arranged between opposite surfaces of two adjacent electrode core sets. Each isolation layer (43) is formed by curing an insulation adhesive coated on at least one of the opposite surfaces of the two adjacent electrode core sets.
