Abstract:
1. A vibration gyro element comprising: a base section; a detection arm extending from the base section in a first direction; a joint section disposed at an end portion of the detection arm opposite to another end portion near to the base section; a first drive arm extending from the joint section in a second direction intersecting with the first direction in a plan view; a second drive arm extending from the joint section in a direction opposite to the second direction; a first drive electrode provided to the first drive arm; a second drive electrode provided to the second drive arm; and a detection electrode provided to the detection arm, wherein the first drive arm and the second drive arm vibrate at the same time, in-phase, in a third direction perpendicular to the first direction and the second direction, so as to detect a physical quantity acting around an axis in the first direction.
