摘要： A capacitor is described, in particular a vacuum capacitor, comprising two electrodes (1, 1′), at least one insulator (5), and means for fastening (4, 4′). A process is proposed according to which the two electrodes (1, 1′) are each produced as one piece of an electrode material through a cold-flow extrusion process. The electrodes so produced are distinguished by a high surface quality. The result of this, in the capacitors produced from such electrodes, is high quality-factors, low temperature coefficients, a high current-carrying capacity, and an excellent dielectric strength, as well as a compact structure with a simultaneous reduction in the number of components required. Capacitors of this type, in particular vacuum capacitors, find application in HF technology for fixed and variable capacitance values.
