Abstract: After an external shape of a photoresist layer is patterned with use of a Cr film as an underlayer, i.e., a metal film to serve as an anticorrosive film that resists crystal etching, and an Au film as a surface layer, the Au film is etched. After groove portions are then patterned, the Cr film is etched. Since no degenerated-surface layer cannot be formed on the photoresist layer with an etchant for the Au film, the groove portions can be patterned without any degenerated-surface layer according to this method, so that high-accuracy groove portions can be formed.

Abstract: An inclination of an inclined surface formed by working a ridge of a resonator is set to be within a predetermined angular range, whereby a leakage of vibration in the out-of-plane direction is reduced, the leakage of vibration being generated according to the detuning degree adjustment. In addition, a single laser beam is irradiated onto the ridge at an incident angle within a predetermined angular range, whereby a simple working on the inclined surface is established for the leakage vibration adjustment. A degree of the leakage vibration of the resonator is determined based on a relationship with the drift amount that is a ratio of the angular velocity change, and the inclination of the inclined surface is set to be within a predetermined angular range, thereby suppressing the drift amount.
