ABSTRACT:
A gyro vibration piece detecting an angular velocity includes a supporting part, a driving part connected to the supporting part and performing vibration, and a detection part detecting vibration generated by Coriolis force generated by the rotation of the driving part. A connection part includes a connection portion having a fin and an end portion connected between at least one of a side of the driving part and a side of the supporting part and a side of the detection part and a side of the supporting part. The end portion includes a top surface and a side surface, whereby the side surface is substantially perpendicular to the top surface and includes a circular arc shape disposed along a bottom portion thereof opposite to a junction of the top surface and the side surface.
