    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.
