Piezoelectric element for use in oscillator and filter oscillating in longitudinal mode

摘要

The piezoelectric element has a piezoelectric substrate (2), a pair of external electrodes (4,5) on the main front and rear sides of a piezoelectric substrate and a conducting carrier section (7,8) mounted on one external electrode on a node region of the substrate and made of a material with a modulus of elasticity of 10<9> N/m2 or greater. The piezoelectric element satisfies T1/T less than = 0.5, where T is its thickness and T1 the thickness of the carrier section An Independent claim is included for a piezoelectric component.
