Abstract
A quartz crystal vibrator element having the weight section is provided with the intermediate weight section formed to have an arm width Wlarger (thicker) than the arm width W of the vibrating arm section and smaller (thinner) than the arm width Wof the tip weight section, thereby making the intermediate weight section follow the vibration (the amplitude) of the vibrating arm section. Further, the tip weight section formed to have an arm width Wlarger (thicker) than the arm width Wof the intermediate weight section is provided, thereby making the tip weight section follow the vibration (the amplitude) of the vibrating arm section and the intermediate weight section. Therefore, the vibration characteristics of the vibrating arm section can be stabilized.
