振器。 In the piezoelectric resonator, the crystal resonator is sandwiched between the two external plates from both sides so that the vibrating part of the crystal resonator and the electrode part formed on the external plates face each other. The piezoelectric resonator is characterized in that the external plate is formed so that the interval between the electrode portions is narrow at the center of the crystal resonator and wide at the ends.
