A vibratory gyro element 100 includes a fixed part 10, a resonator 20 having a cos Nθ (N is a natural number of two or more) mode of vibration, support parts 30, and electrodes 40. The electrodes 40 are arranged in 4N orientations arranged in an outer cir...

The displacement amount monitoring electrode structure according to the present invention is for maintaining the amplitude of the detection mass at a constant target amplitude even when the relative relationship between a fixed electrode and a movable elec...
