Abstract

The piezoelectric vibrator element is miniaturized, and at the same time, the vibration leakage is suppressed. The piezoelectric vibrator element is formed so that the total length Lof the piezoelectric vibrator element, the length Lof the base, the width Lof the connection part, the length Lof the support arm part fulfill all of the following conditions A through C, Condition A: 0.1≦L/L≦0.2, Condition B: 0.4≦L/L≦0.6, Condition C: L/L≧0.7. While the miniaturization is realized by shortening the base due to the condition A, the distance via the base can be elongated due to the condition B. Further, by increasing the length of the support arm parts due to the condition C, it is possible to increase the total mass of the path transmitting the vibration to absorb the vibration to thereby further suppress the vibration leakage.
