PROBLEM TO BE SOLVED: To provide a capacitor which inhibits the aged deterioration of voltage endurance.SOLUTION: A capacitor 1 includes: a dielectric body 2 including a pair of electrodes 21, 22; an insulation cylinder 3 housing the dielectric body 2; and a pair of conductors 31, 32 vacuum sealing the cylinder 3 while contacting with the electrodes 21, 22. The dielectric body 2 forms a cylindrical body coaxially arranged with the cylinder 3 and placed in the cylinder 3. The electrodes 21 are provided on one end surface and parts of an outer peripheral surface of the dielectric body 2. The electrodes 22 are provided on the other end surface and parts of an inner peripheral surface of the dielectric body 2. |
