Abstract
A capacitor forming unit includes a dielectric plate, a first conductor film formed on a plate upper surface region other than front and rear end portions, a first insulator film formed on the upper surface front end portion, a second insulator film formed on the upper surface rear end portion, a second conductor film formed on a plate lower surface region other than front and rear end portion, a third insulator film formed on the front end portion lower surface, and a fourth insulator film formed on the lower surface rear end portion. One or more first electrode rods are disposed in through holes, and electrically connected to the first conductor film and electrically insulated from the second conductor film. One or more second electrode rods are disposed in other through holes, and electrically connected to the second conductor film and electrically insulated from the first conductor film.
