Abstract

PURPOSE: To obtain a composite oscillator which features excellent frequencytemperature characteristics that is never obtained a single unit structure, which can be used suitably to the small-sized apparatus such as an electronic wristwatch or the like, by using plural units of oscillators featuring the bending vibration mode, vertical vibration mode, contour shear mode and others.
