SEALED BATTERY

The purpose of the present disclosure is to expand the insulation area of an electrode body and an outer package can, to improve the insulation performance of a battery. A sealed battery is one example of an embodiment, and is provided with an electrode body, a bottomed cylindrical outer package can that houses the electrode body, a sealing body that seals up an opening part of the outer package can, and insulating plates each placed between the respective end faces of the electrode body and the outer package can. A first face of each of the insulating plates faces the electrode body. The outer edge of the first face stands on the insulating plate outside the outer edge of a second face of each of the insulating plates which is on the opposite side of the first face. The sealed battery, which is one example of an embodiment, is provided with a top insulating plate and a bottom insulating plate as the insulating plates.
