Abstract
A sealed battery includes an electrode assembly; a case having an opening portion and accommodating the electrode assembly; a lid closing the opening portion and having a through-hole; a collector terminal including an inner terminal segment and a projection; and an insulating seal in contact with a bottom surface of the lid, the bottom surface being an inner side of the lid in a thickness direction of the lid, the inner side of the lid facing an inside of the case when the lid closes the opening portion, and the insulating seal providing sealing between the lid and the collector terminal. The lid has a protrusion protruding from the bottom surface of the lid. The protrusion surrounds the through-hole. A part of the protrusion protrudes into the through-hole. The through-hole has a smallest opening diameter at a position at which the part of the protrusion protrudes into the through-hole.
