A seal plate () seals an opening part of a capacitor case (an exterior case) and includes a main body part () including a through-hole () for discharging a gas (G) in the capacitor case, a pressure valve () arranged to cover the through-hole and including a valve body part () allowing passage of the gas, a storage part () 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) that includes an opening part () 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.
