Abstract
An object of the present invention is to provide a compact and highly reliable oscillator device having stable vibration characteristics, the object being achieved by constructing the oscillator device by bonding an oscillator in place by accurately positioning it, in a prescribed position and at a prescribed angle, inside a package. The oscillator device according to the present invention includes an oscillator having a vibrating prong and a base portion with a first reference portion, a package, a mounting base with a second reference portion provided inside the package, and a bonding material for fixing the oscillator to the mounting base by aligning the first reference portion with the second reference portion by utilizing a self-alignment effect occurring due to surface tension.
