A strip-shaped metal electrode (13) is placed below the foil in the aperture and is connected to the stripped end (14) of a plastic insulated lead (15), whose end portion is covered by the cover foil. The whole assembly is welded together to form a unit in that it is placed between two pressing plates which form a capacitor in a high-frequency circuit, and one of them is of the same size and shape as the cover foil and presses it a distance into the foam plastic disc, which is thus compressed in the area concerned and fixed in the compressed shape because the cell walls partly fuse. This increases the resistance of the foam plastics against diffusion of the components of the contact medium which in the use of the electrode is placed in the aperture (11), without any noticeable deterioration in the flexibility and pliability of the electrode. | |
