摘要： There is provided a piezoelectric vibrating reed (32), including: a base (51) formed of a piezoelectric material and having a predetermined length; a plurality of vibrating arms (35),(36) extended from one side of the base; a support arm (61) extended in a width direction from the other side spaced apart from the one side of the base by a predetermined interval and extended outside the vibrating arms in the same direction as the vibrating arms; and a cut portion (71) formed in the piezoelectric material reducing its width direction at a location closer to the vibrating arms than a connection portion where the support arms are connected to the base as one body, wherein a through-hole (80) is also disposed at a location closer to the vibrating arms than the connection portion where the support arms are connected to the base as one body.
