Abstract
A method of manufacturing a piezoelectric vibration reed is provided. The piezoelectric vibration reed includes a pair of vibrating arm portions and a base portion. The pair of vibrating arm portions is disposed in parallel to each other. The base portion is configured to integrally support proximal end portions of the pair of vibrating arm portions in a longitudinal direction of the vibrating arm portions. The method of manufacturing the piezoelectric vibration reed forms a slit-shaped notched portion at a crotch portion located between the proximal end portions of the pair of vibrating arm portions.
