Abstract
A through-hole () is disposed in a supporting substrate (). Plate-shaped beams ((A,B)) each includes a piezoelectric element, extends from an edge of the through-hole () toward an opposite edge to close a part of the through-hole (), supports a substance adsorption film to which a constitutive substance to be detected adheres, and has a vibration frequency that is varied due to adhesion of the constitutive substance to the substance adsorption film. Drive electrodes () apply a voltage to the piezoelectric element to vibrate and deform the beams (). Detection electrodes () detect information about the vibration frequencies of the beams ().
