Abstract
A capacitor forming unit according to one embodiment includes a dielectric plate with a plurality of through holes; a first conductor film formed on an upper surface of the dielectric plate; a first insulator film formed on the front end portion of the upper surface of the dielectric plate; a second conductor film formed on a lower surface of the dielectric plate; a second insulator film formed on the rear end portion of the lower surface of the dielectric plate; first electrode rods disposed in some of the through holes; and second electrode rods disposed in the remaining through holes where the first electrode rods are not disposed. The first electrodes are electrically connected to the first conductor film and electrically insulated from the second conductor film. The second electrode rods are electrically connected to the second conductor film and are electrically insulated from the first conductor film.
