<p>This battery is provided with a lid member (113) that closes a case, a collector terminal member (135) having an insertion section (132), an insulator (180) that electrically insulates the lid member and the collector terminal member, and a gasket (170) that provides a seal between the lid member and the collector terminal member. The lid member has a protruding section (223) that protrudes downward in the vertical direction from the bottom. The gasket is in the same position as the protruding section in an inside-outside direction, which is perpendicular to the vertical direction, and has a seal section (231) that is pressed by the protruding section. At least one gap (241 or 243) exists in the vicinity of the seal section in a different position to the seal section in the inside-outside direction, and at least portions of said gaps (241, 243) are enclosed by the gasket and the collector terminal member.</p> |
