摘要：
A piezoelectric vibrating piece includes a pair of vibration arm portions that is placed in a row in a width direction; a base portion to which proximal end sides in the pair of vibration arm portions in an extending direction are connected; and weight metal films that are formed on outer surfaces of the vibration arm portions, wherein the weight metal films are formed in positions that avoid regions of tip portions in the vibration arm portions in a longitudinal direction.
