摘要： A dielectric material for high frequencies, wherein a glass, an oxide aggregate having a dielectric constant whose temperature coefficient tau epsilon is positive, and an oxide aggregate having a dielectric constant whose temperature coefficient # tau# epsilon is negative are used, these are blended in a predetermined volumetric ratio, the temperature coefficient tau epsilon of high frequency dielectric material is about -12 ppm/ DEG C. Thereby the temperature coefficient tau f of the resonance frequency of the high-frequency resonator made of the dielectric material is about zero.

摘要： A multilayer ceramic part in which its inner conductor is compacted, and the loss of a line is reduced, the performance such as the Q value is improved, and the variation of the performance is reduced. The paste of the inner conductor is made of powder of conductor, preferably silver or copper, and a glass frit, if necessary. The layers of the paste of the inner conductor and dielectric ceramic material layers are stacked and are baked simultaneously at a temperature higher than the melting point of the conductor.

摘要： A multilayer ceramic part including dielectric ceramic layers and internal conductor layers is prepared by forming dielectric ceramic layers from an oxide system dielectric ceramic material having a sintering completion temperature between the melting point and the boiling point of the internal conductor. A pattern of internal conductor is formed on dielectric ceramic layers. The dielectric ceramic layers are placed one on another so as to sandwich the internal conductor pattern therebetween. The laminate is fired at or above the melting point of the internal conductor, optionally in an atmosphere having a controlled oxygen partial pressure. Since the dielectric ceramic material has an improved dielectric constant and dielectric loss and the internal conductor is densified and improved in surface property, the part is improved in resonator Q value and other properties. This minimizes the occurrence of defective parts in which the internal conductor is separated from the dielectric ceramic layer and minimizes a failure in the internal conductor layer.
