CYLINDRICAL BATTERY

The purpose of the present disclosure is to provide a cylindrical battery in which a short circuit between an outer can and a sealing body can be suppressed. In a cylindrical battery () according to an embodiment of the present disclosure, a gasket () includes an extension part () extending from between a sealing body () and a tip (a) on a radially inward side of a shoulder () of an outer can (). The extension part () is arranged so that the gasket () intersects any straight lines connecting an upper surface () of the shoulder () opposite to the electrode body side in the axial direction and an upper surface () of an inner portion () opposite to the electrode body side in the axial direction, the inner portion () being located radially inward of the shoulder () in the sealing body ().
