Abstract
An oscillator includes an oscillatory element in the form of a triangular prism. Two supporting members are fixed at their center to the oscillatory element. The two supporting members include annular coils, each with a single turn. The supporting members have inner peripheral portions which are fixed to the ridge of the oscillatory element at a location adjacent to its nodes. The oscillatory element has three sides on which three piezoelectric elements are correspondingly formed. When a drive signal is applied to two of the piezoelectric elements, then the oscillatory element is bent or oscillated in a direction perpendicular to the surface of the other piezoelectric element.
