To provide a piezoelectric vibration device which has an excellent performance of vibration resistance and impact resistance to disturbance vibration.

A yaw rate sensor device 1 includes: a sensor holder 5 which includes a sensor part 2 having a piezoelectric element; a support 3 which supports the sensor holder and has elasticity; and a case 4 wherein the sensor holder and the support are provided, and has a recess 7 in the bottom wall of the case to keep at least a part of the support held inside the recess. For the support 3, resin or a resin composition can be used. Moreover, a filler may be added to the resin or the resin composition.
