PURPOSE: To facilitate the mounting of a capacitor on a circuit board and to obtain the excellent withstand voltage characteristics by covering both main surfaces of a dielectric ceramic plate with thin film electrodes, and covering at least one surface of the electrodes with a thin film brazing material. CONSTITUTION: A dielectric ceramic plate 1 is covered on both main surfaces with a pair of thin film electrodes 2. When the plate 1 is formed by barium titanate ceramics, the electrodes 2 covering both the main surfaces are formed in a three layer structure in which a titanium layer 2a, a palladium layer 2b and a metallic layer 2c are sequentially covered from the plate 1 side. Further, the plate 1 in which both the main surfaces are covered with the electrodes 2, is covered at least on the one surface of the films 2 with a thin film brazing material 3. The material 3 is made of gold-tin alloy with a thickness of 0.5 to 10.0μm.
