た。Conventional configuration and problems Conventionally, in an oscillator using a piezoelectric ceramic diaphragm, external capacitors C 1 and C 2 are connected in series on both sides of a ceramic oscillator A, as shown in the piezoelectric oscillator circuit diagram shown in Figure 4. It is composed of This is a structure in which electrodes are provided only on both opposing end surfaces of a piezoelectric ceramic diaphragm, and each electrode is connected to a terminal, and this configuration was adopted because a capacitor function cannot be taken out.
Connecting an external capacitor has the drawbacks of increasing the cost of manufacturing the oscillator and increasing the size of the oscillator. As a means to eliminate these drawbacks, a structure in which the capacitor is housed in a case has been devised, but this also has the drawback of increasing the cost of the ceramic oscillator.
