Abstract

PURPOSE:To improve the Q value to improve the frequency aging characteristic and reduce dimensions of the vibrator considerably, by improving the supporting structure of the tuning fork type quartz vibrator. CONSTITUTION:When the width of arm parts 11, an interval 12 of arm parts 11, the width of a tuning fork base part 13, and the length of the tuning fork base part in a tuning fork quartz vibrator 10 are denoted as (w), (d), W, and L, respectively, the tuning fork type quartz vibrator is constituted to satisfy (2w+d)<W<(2w+ 3d) and L>=W. A part where the width of the tuning fork base part changes gradually in the longitudinal direction is provided in the region of connection between tuning fork arm parts 11 and the tuning fork base part 13.
