Abstract

PURPOSE:To necessitate only one time of fine adjustment of metal films by disposing two or more rows of screen-form additive mass parallel to a Y-axis direction to the Z plane of end resonance parts for every one resonance branch where the lengthwise direction of a tuning fork type crystal vibrator having two resonators is made Y direction and its main face is made Z plane.
