摘要: A decrease in vibration efficiency due to size reduction of a tuning-fork type piezoelectric vibrating piece is prevented. A piezoelectric vibrating piece includes a base portion, and a pair of vibrating arm portions extending in parallel from the base portion. Each of the vibrating arm portions includes an arm portion extending from the base portion, and a head portion connected to a distal end of the arm portion and having a width larger than that of the arm portion. The piezoelectric vibrating piece satisfies the following relation: 0.13×1012≤Vh(Lh2+Wh2)≤0.39×1012, where Lh [μm] is a length of the head portion, Wh [μm] is a width of the head portion, and Vh [μm3] is a volume of the head portion.
