Tuning fork-type piezoelectric vibration piece and tuning fork-type piezoelectric vibrator using the vibration piece
Main surface electrodes formed on main surfaces on front and back sides of vibrating arms are electrically coupled via through electrodes formed in a stem portion so as to penetrate through front and back surfaces thereof. One of the main surface electrodes of the vibrating arm is electrically coupled to side surface electrodes through a routing wiring formed by way of a crotch part between roots of the vibrating arms, and the one of the main surface electrodes is further electrically coupled to the other one of the main surface electrodes through the side surface electrodes.
