PROBLEM TO BE SOLVED: To propose structure where capacitor characteristics do not change even if pressure in a unit changes. SOLUTION: The pressure change in the unit is restrained by providing an air buffer layer A between an end plate 1 and a collector plate 2, and further a hole 8 is provided at the collector plate 2, and pressure in the inside of the air buffer layer A and the unit is automatically released to reduce variation in inner pressure. |
