Abstract

See full text

A seal plate (2) seals an opening part of a capacitor case (an exterior case 52) and includes a main body part (4) including a through-hole (8) for discharging a gas (G) in the capacitor case, a pressure valve (12) arranged to cover the through-hole and including a valve body part (26) allowing passage of the gas, a storage part (16) formed in the through-hole to receive the valve body part expanded due to a pressure in the capacitor case, and a stopper (stopper wall 10) that includes an opening part (20) for discharging the gas passing through the valve body part and that comes into contact with a portion of the valve body part in the storage part to deform the valve body part. This achieves an increase in gas permeability of the pressure valve and a high operating pressure maintained in the pressure valve.
