The dielectric body 1 of the capacitor is constructed of a non-linear dielectric ceramic which exhibits resistance to reduction. The non-linear dielectric ceramic comprises a polycrystalline substance containing barium titanate as a primary component, and when the polycrystalline substance is represented by (1−a−b)ABO3+aM+bR wherein ABO3 is a barium titanate component and represents a perovskite structure, M is an oxide of at least one element selected from the group consisting of Mn, Ni and Co, R is an oxide of at least one element selected from the group consisting of La, Ce, Nd, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er and Yb, and a and b represent mole fractions; A, B, a, and b satisfy the following relationships: 1.000≦A/B≦1.006 (mole ratio), 0.3≦b/a≦3, 0.0015≦a≦0.0050, and 0.0015≦b≦0.0050, and a total content of M and R represented by Ad satisfies 0.3

摘要： A high-voltage capacitor is not deteriorated by any of a laser medium gas, ultraviolet rays, and discharge plasma of a gas laser device. Inside a hermetic casing is stored a capacitor body having an electrode which is connected to an external terminal. The external terminal includes a passageway therein which makes the inside of the hermetic casing communicate with the outside of the hermetic casing. The external terminal is led to the outside of the hermetic casing from the capacitor electrode, and gas inside the hermetic casing is discharged through the passageway of the external terminal to achieve a reduced pressure. Thereafter, the inside of the hermetic casing is filled with an insulating protection material. With the hermetic casing being made of alumina and the electrode terminal plated with nickel, deterioration due to ultraviolet rays or discharge plasma generated by an electric discharge of the laser device is prevented, thereby not contaminating the ambient gas.

摘要： A manufacturing method for a ceramic capacitor superior in breakdown voltage ability, comprising a process of baking opposite electrode on the surface of ceramic dielectric composed mainly of metal oxide and that, simultaneous with or after the above process, of baking in a ring-like shape insulating layers for air cutoff on at least the edges of an electrode.The opposite electrodes are formed by baking on the ceramic dielectric an electrode material composed mainly of metal of oxidization property more intense than that of the metal oxide at the ceramic dielectric material, in which, when the insulating layers on the electrode are baked, parts covered with the insulating layers at the opposite electrodes are cutoff from air, so that the ceramic dielectrics just below the parts are deprived by the opposite electrodes of inner oxygen so as to be intensively reduced and the reduced areas each become a semiconductor to largely decrease an insulating resistance value, thereby relaxing a potential gradient at the edge of the electrode and improving the breakdown voltage ability.

摘要： A ceramic capacitor comprising a dielectric ceramic element made of materials a metal oxide as the principal ingredient. On the surface of the dielectric ceramic element are formed a plurality of electrodes. The materials used for the electrode are selected such that their principal ingredients have a stronger oxidizing tendency than those used for the dielectric ceramic element. The electrode is formed by applying this electrode material on the surface of the dielectric ceramic element and subsequently baking in a non-reducing atmosphere. This process reduces the surface of the dielectric ceramic element underneath the electrode and a reduced layer is thus formed.
