Claims

[Scope of utility model registration request]

Concave-shaped flat parts that serve as vibrating parts are provided on both sides of the central part of the thickness-shear crystal resonator piece, and the flat parts are formed in a parallel state. Electrodes are formed on these flat parts, and these electrodes Electrode lead parts electrically connected to are formed on both sides, the recessed flat part that becomes the vibrating part is covered with a flat protector, and the protector and the crystal resonator piece are sealed with a sealing material. A crystal oscillator characterized by:
