Beschreibung
Zusammenfassung:	A sealed battery includes a battery case, an external terminal, a collector terminal, a protruding member, and a pressure type current interrupting mechanism. The pressure type current interrupting mechanism electrically disconnects the external terminal from the collector terminal by an inverted plate deforming according to an increase in pressure inside the battery case. The protruding member has a through-hole that is communicated with a hollow portion of the external terminal. When the pressure type current interrupting mechanism is activated, the protruding member pierces the inverted plate, such that the hollow portion of the external terminal is communicated with the inside of the battery case further inside the battery case than the collector terminal of the battery case, via the through-hole of the protruding member.
