摘要： An energy trap type piezoelectric resonator component includes a piezoelectric resonator using a third overtone of a thickness longitudinal vibration. The piezoelectric resonator includes a piezoelectric substrate, and first and second vibrating electrodes, having an elliptical shape, and respectively arranged on portions of first and second major surfaces of the piezoelectric substrate such that the first and second vibrating electrodes face each other with the piezoelectric substrate interposed therebetween. A flattening ratio “a/b” of a minor axis diameter “b” to a major axis diameter “a” of the elliptical shape is within a range of from about 1.2 to about 1.45. The resonator is thus compact, effectively controls the fundamental wave of the thickness longitudinal vibration as a spurious wave, is relatively free from area restraints of the electrode and dimensional constraints, and meets a variety of frequency requirements in a wide range.

摘要： A small and easily produced piezoelectric resonator, which effectively damps unwanted vibration and utilizes intended vibration includes excitation electrodes provided on both main surfaces of a piezoelectric substrate, and first and second lead-out electrodes and first and second terminal electrodes electrically connected to the excitation electrodes, respectively. At least one of the terminal electrodes includes an electrode extension portion arranged to extend into the imaginary region where the first and second excitation electrodes are extended to at least one of the side edges of the piezoelectric substrate.

摘要： A piezoelectric component includes leads and being arranged to suppress the adhesion of solder or a conductive adhesive agent to lead-out electrodes or vibration electrodes thereof, which is therefore resistant to the deterioration of electrical characteristics such as resonance characteristics, and which minimizes fluctuation of the electrical characteristics. In this piezoelectric component having the leads, the vibration electrodes are provided on each of the first and second main surfaces of a piezoelectric plate, and each of the vibrating electrodes is connected to a terminal electrode via a lead-out electrode. Each of the holding portions of a lead terminal is bonded to the terminal electrode, and is arranged so as not to extend onto the lead-out electrode.
