Abstract

AN ENERGY TRAP TYPE PIEZOELECTRIC RESONATOR (1) INCLUDES A PLATE-LIKE PIEZOELECTRIC RESONATOR ELEMENT (2) CONSTRUCTED TO VIBRATE IN A THIRD HARMONIC OF A LONGITUDINAL VIBRATION MODE IN A THICKNESS DIRECTION THEREOF AND SUCH THAT BOTH MAIN SURFACES OF THE RESONATOR ELEMENT (2) ARE LAMINATED WITH SEALING SUBSTRATES (3 & 4). SEALED SPACES ARE PROVIDED SO AS TO ALLOW A VIBRATING PORTION OF OPPOSITELY DISPOSED VIBRATING ELECTRODES (6 & 7) TO VIBRATE. SEALING PORTIONS, IN WHICH THE PIEZOELECTRIC RESONATOR ELEMENT (2) AND THE SEALING SUBSTRATES (3 & 4) ARE JOINED AND CONNECTED AROUND THE SEALED SPACES (10 & 11), ARE CONSTRUCTED SO THAT WHEN THE THICKNESS OF A PIEZOELECTRIC SUBSTRATE (5) IS REPRESENTED BY T AND THE SHORTEST DISTANCE TO THE SEALING PORTION FROM THE VIBRATING ELECTRODES (6 & 7) IS D, THE SEALED SPACES SATISFY THE RELATIONSHIP 0 < D/T < 5.(FIG. 1B)
