<p>Disclosed is a sealed battery capable of suppressing time degradation of a CID. A battery (1) includes an electrode body (10), a case (20), and a CID (100) which interrupts a current in emergency. The CID (100) includes an inversion plate (110) which is transformed in association with an increase of a pressure in the case (20), and a collecting plate (120) which is connected to the inversion plate (110) and which is transformed in association with a transformation of the inversion plate (110). The collecting plate (120) has a carved part (123) formed in a groove, which is ruptured if the pressure in the case (20) is a predetermined value or more, and a plurality of slits (124). The plurality of slits (124) is arranged in the vicinity of the carved part (123), and is formed to open when the collecting plate (120) is transformed.</p> |
