Abstract
A vibrating gyroscope comprises a ring-shaped vibrating body () a leg portion () flexibly supporting the body () and having a fixed end, a fixed potential electrode (), and a plurality of electrodes (-) with a piezoelectric film sandwiched between an upper and a lower-layer metallic film in a thickness direction thereof. When N is a natural number of 2 or more, the plurality of electrodes (-) include driving electrodes () for a primary vibration in a vibration mode of cosNθ, which are each disposed (360/N)° apart from each other in a circumferential direction, first detection electrodes () and second detection electrodes () for detecting a secondary vibration generated when an angular velocity is applied to the body (), which are each disposed in a certain region related to the driving electrode () Each of the electrodes is also disposed in a certain region of the body ().
