ABSTRACT:
An improved capacitor and a method of manufacturing the same, aimed at implementation in small size and/or with large capacitance, are disclosed. A pair of composite structures are formed. Each composite structure includes insulating layers of ceramic material formed on a base plate of a flexible material. At least one electrode is formed on the insulating layer. A dielectric layer of a ceramic green sheet of extremely small thickness, as thin as approximately 3 microns, is formed on the insulating layer covering the electrode. The two composite structures are joined to form a laminate such that respective base plates are located on the outside of the resultant laminate and the respective electrodes face each other through respective extremely thin dielectric layers. The resultant laminate is fired in a heating furnace after the respective base plates are removed. As a result, a capacitor is formed whose electrostatic capacitance is defined between the two electrodes.
