Abstract
A layer or stack type capacitor having a covering foil, and adhesion-imparting layer disposed on the surface of the covering foil, a first electrically conductive layer disposed on the surface of the adhesion-imparting layer and a dielectric and second electrically conductive layer disposed respectively against the surface of the first electrode. The first conducting layer or electrode is made sufficiently thin so that the adhesion-imparting layer may adhere to the dielectric layer through pores of the first electrically conductive layer. The result is that the covering foil, adhesion-imparting layer, first electrically conductive layer and dielectric adhere together and are hermetically joined to eliminate the possibility of moisture entering into the vicinity of the first electrode to cause harmful corrosion.
