SENSOR ELEMENT AND ANGULAR VELOCITY SENSOR

A sensor element includes a piezoelectric body and a plurality of electrodes. The piezoelectric body, when viewed on a plane, includes a base part and at least one arm part extending from the base part. The plurality of electrodes are located on a surface of the arm part. The piezoelectric body, when viewed on the plane, further includes a frame part which surrounds the base part and the at least one arm part and upon which the base part is bridged.
