Abstract

PURPOSE:To improve the positional precision and eliminate frequency abnormal phenomena surely and further perform adjustment of freqencies dependent upon an additional mass simply with a high precision, by forming the thick part in the driving electrode forming process. CONSTITUTION:In the process where driving electrodes 32 and 33 are formed on both faces of thickness slip mode and convex type crystal piece 30, thick part 32a to eliminate frequency abnormal phenomena is provided on one of driving electrodes 32 and 33 at least. This thick part 32a has the mass loading effect, where fundamental resonance frequency f0 of fundamental main vibration and resonance frequencies f32 and f33 of inharmonic vibration appearing near the triple frequency of frequency f0 become more distant from one another relatively by 1/3, on frequencies f0, f32 and f33. After forming this thick part, a driving signal is supplied to driving electrodes above to vibrate crystal piece 30, and additional mass 34 for frequency adjustment is formed one of driving electrodes at least, and forming of additional mass 34 is stopped when the frequency reaches a desired fundamental resonance frequency.
