Claims

[Claims for Utility Model Registration] 1. In a piezoelectric vibrator having a structure in which a piezoelectric plate that excites thickness shear vibration is housed in a surface-mounted container, the plate is mounted on a support stand separated from the container when supporting the piezoelectric plate. A piezoelectric vibrator characterized in that the piezoelectric vibrator is housed and fixed in the container after being supported and fixed by providing a shaped support. 2. In a multi-mode piezoelectric wave device having a structure in which a piezoelectric element formed by forming two pairs of excitation electrode films on a piezoelectric plate capable of exciting thickness-shear piezoelectric vibration is housed in a surface-mounted container, the piezoelectric element is supported. 1. A piezoelectric wave device characterized in that a plate-like support consisting of three terminals is provided on a support stand separated from a container to support and fix the piezoelectric wave device, and then the piezoelectric wave device is housed and fixed in the container.
