Abstract

PURPOSE:Adjust the resonance frequency simply by forming electrodes opposed to each other to both faces of a piezoelectric substrate or forming a parallel electrode to one side so as to provide a capacitor and connecting it in series with a vibrating element. CONSTITUTION:Exciting electrodes 8, 8' having a diameter in response to an objective characteristic are opposed in response to the objective characteristic to the center of the surface of a discoid piezoelectric substrate 7 and plural rectangular pole plates 9,9',9... with a minute area opposed to each other are provided on both sides of the circumference of the piezoelectric substrate 7. The exciting electrode, pole plate and lead pattern are vapor-deposited on the piezoelectric substrate so as to lower the frequency more than the desired resonance frequency, and the lead wire is connected, some of rectangular pole plates formed with a capacitor in response to the measured value of the resonance frequency are disconnected from the strip lead pattern by radiating a laser ray to etc., decrease the capacitance thereby adjusting the resonance to the desired resonance frequency.
