Abstract

PURPOSE:To make an energy locking-in type piezoelectric resonator small-size and improve the quality of this resonator, by hardening the nonviscid insulating resin, which is provided in the vibration part of a piezoelectric substrate, in the resonance state. CONSTITUTION:Electrode patterns 2 are formed on both faces of piezoelectric substrate 1, and external taking-out lead wires 3 are connected to them. Next, unhardened nonviscid insulating resin 11 is provided in operating electrode 10 of electrode pattern 2 and a range wider than the region where main vibration is attenuated sufficiently. The input of the resonance frequency is applied from the external, and the vibration part of substrate 1 is caused to resonate at a level stronger than that of the use state, and resin 11 is hardened in this resonance state. Next, after hardening of resin 11, substrate 1 is molded with insulating resin 12 so that the whole of substrate 1 may be covered with resin 12. Since resin 11 is hardened under the resonance state in this manner, resin 11 is not brought into contact with the vibration part. Thus, the resonator can be small-size, and irregularity of the quality can be reduced.
