Abstract
An angular velocity sensor which suppresses the generation of noise in a detector piezo-electric element due to vibration of a vibrator caused by expansion and contraction of a driver piezo-electric element. A driver piezo-electric element 6 is adhered to an upper part on the left-side surface of a first square pole 3 of a vibrator 1 and a driver piezo-electric element 7 is adhered to an upper part on the right-side surface of a second square pole 4. Further, a detector piezo-electric element 8 is adhered to a lower part on the front surface of the first square pole 3 of the vibrator 1 and a detector piezo-electric element 9 is adhered to a lower part on the front surface of the second square pole 4. Here, the driver piezo-electric elements 6, 7 and the detector piezo-electric elements 8, 9 are disposed so as to be deviated so that they will not overlap in the axial direction of the square poles.
