    摘要： Material forming dielectric ceramics includes an oxide containing a component A and a component B. The component A is selected from a group I of lead, calcium, strontium, and barium. The component B is selected from a group II of magnesium, nickel, titanium, zinc, niobium, and tungsten. The component A includes lead and at least one of the other substances in the group I. The component B includes at least two of the substances in the group II. A ratio between values a and b is chosen so that a/b>1.00, where the value a denotes a total mol value of the substances in the component A and the value b denotes a total mol value of the substances in the component B. Electrode layers are made of copper or an alloy principally containing copper. Since the firing temperature of the dielectric ceramics is low, excellent characteristics of a capacitor are enabled in spite of the fact that electrodes contain copper.
