ABSTRACT:
The oscillation type gyroscope comprises an oscillator having electrodes for driving and for detection and also having oscillating arms adapted to oscillate in a cantilevered state, with front end portions of the oscillating arms being free ends; a support member for supporting a base end portion of the oscillator; a circuit board to which the support member is secured; a flexible printed circuit board with wiring patterns formed thereon and having oscillator-side end portions, a circuit board-side end portion and a wiring portion; first connecting portions provided in the oscillator-side end portions, conducted with the wiring patterns and connected to corresponding electrodes electrically by soldering at the base end portion of the oscillator; and a second connecting portion provided in the circuit board-side end portion, conducted with the wiring patterns and connected electrically to the circuit board at the circuit board-side end portion, wherein among the electrodes, those which lie in the same plane and which become equal in potential at the time of polarization and in use, are gathered as one group at the base end portion of the oscillator.
