Abstract

A capacitor comprises a capacitor element which is accommodated in a cylindrical casing with electrodes attached to the two end faces thereof. The capacitor element includes a high as possible doped monocrystalline silicon disk, a layer of insulating material arranged on the first main surface thereof, and of a rectangular, first contact electrode at least partly covering the insulating layer. On the second main surface of the capacitor element there is arranged a layer-shaped second contact electrode. The cylindrical casing consists of a glass envelope or tube whose inner diameter is adapted to the diameter of the silicon disk, as well as metal inserts inserted at each end of the casing, contacting the capacitor element and serving as the electrodes.
