ABSTRACT:
A piezoelectric resonator device with a laminated structure include two piezoelectric plates, each having opposite flat surfaces and polarized in a predetermined direction. Each piezoelectric plate is deposited with electrodes on its opposite flat surfaces, respectively. A junction layer of solder is rigidly held between the two piezoelectric plates for holding them together in a laminated structure. A weight ratio of the junction layer to a sum of two piezoelectric plates including their electrodes is selected to be between 0.5% and 5%.
