Powders of BaCO3, TiO2, ZnO, etc. are mixed to each other at a predetermined ratio of quantity, calcined in an atmospheric air at &pgr;°-120° C., and pulverized to obtain a calcined powder having an average grain size from 1 to 3 &mgr; m, 0.1 to 20 parts-by weight of a powder having an average grain size from 0.1 to 1.5 &mgr;m comprising a glass having a transition point of not higher than 450° C. obtained by mixing powders of Pb3O4, SiO2, Na2O, etc. to each other, melting and then pouring into water and pulverizing the thus obtained glass is admixed to the calcined powder. The mixture is dried, pelleted by adding a resin and the pellet powder is molded into a cylindrical shape, applied with CIP (Cold isotartic press), and the molding product after the treatment is sintered in an atmospheric air at 850° to 1000° C. to obtain a dielectric ceramic sintered at low temperature. The resultant dielectric ceramic has high denseness and high unloaded Q value while maintaining &tgr;f within a practical range.

A grinding body for on-line roll grinding has a grindstone of a cup shape. The grindstone is on a surface portion, and near a peripheral edge, of a circular support base plate, so that a peripheral edge portion of the circular support base plate has on a surface side thereof a two-layer structure. This two-layered structure includes a flat ring-shaped portion jutting toward an inner periphery so as to define a groove opening inward. The grindstone is mounted on the flat ring-shaped portion; and a damping material is filled and mounted into the groove. This grinding body can effectively prevent the formation of a spiral mark and a pitching surface mark, improve the grinding power and grinding accuracy, and prolong the life of the grindstone.

The first trimming capacitor electrode is first trimmed for rough adjustment of a capacitance of the circuit. The second trimming capacitor electrode is then trimmed for fine adjustment of the capacitance.
