PROBLEM TO BE SOLVED: To provide a crystal oscillator which reinforces support of a crystal vibrator piece in a vibrator with a pair of sealing bodies to reduce vibration leakage and obtain a stable vibration mode.SOLUTION: A crystal oscillator 11 includes: a plate-like vibrator 12 having a crystal vibrator piece 15 and a connection piece 17, which supports at least one end of the crystal vibrator piece 15, and formed by a support frame 16 enclosing an outer periphery of the crystal vibrator piece 15; and a pair of sealing bodies 13, 14 respectively having sealing frames 21, which tightly contact with upper and lower surfaces of the support frame 16, and configured to seal the vibrator 12. The pair of sealing bodies 13, 14 is provided with a pair of reinforcement pieces 22 which faces at least a part of the connection piece 17 and support the connection piece 17 when the pair of sealing bodies 13, 14 sandwiches the vibrator 12.SELECTED DRAWING: Figure 1 |
