摘要： A base (10) is provided with a plug (12) having a substantially cylindrical shape and two lead wires (14) passed through the plug (12). A piezoelectric vibrating body (24) is fixed to the front ends of the lead wires (14) with a supporting member (26) composed of a soldering material containing lead with the ratio of more than 60 wt.%, preferably 85-98 wt.%. A cap (28) which is opened on one side is put on the vibrating body (24). The cap (28) forms an airtight container when the opened end is sealed with the plug (12) and, also, a piezoelectric vibrator airtightly housing the vibrating body (24). Since the solder containing a high percentage of lead is soft and low in Young's modulus, the solder disperses stresses when shocks are applied to the piezoelectric vibrator. Therefore, the concentration of stresses to the vibrating body (24) can be avoided and the shock resistance of the piezoelectric vibrator can be improved. In addition, since layers of solder containing
