ABSTRACT:
A vibrating gyro element includes in the same plane a base portion; a pair of vibrating arms for detection extended out of the base portion on both sides in a straight line shape; a pair of connecting arms extended-out from the base portion onto both sides in directions perpendicular to the vibrating arms for detection; a pair of vibrating arms for driving each extended-out from the tip portion of each of the connecting arms to both sides perpendicularly to this tip portion; four beams extended out of the base portion; and a support portion connected to the tip of each of the beams; wherein each of the beams is once extended out of the base portion in a direction approximately perpendicular to the extending-out direction of the vibrating arm for driving.
