Claim Text:
1. A piezoelectric vibrating piece comprising: a pair of vibrating arm portions; a base portion to which respective base end sides of the pair of vibrating arm portions are fixed; a support arm portion connected to the base portion between the pair of vibrating arm portions and extending from the base portion to a tip end on a same side as the pair of vibrating arm portions; first and second excitation electrodes on each of the pair of vibrating arm portions; first and second mount electrodes displaced at an interval in a longitudinal direction of the support arm portion on a mount surface of the support arm portion, the first and second mount electrodes bonded to respective first and second electrode pads on a substrate by a conductive adhesive; and first and second layout electrodes connecting the first and second mount electrodes, respectively, to the first and second excitation electrodes via the base portion, wherein the second layout electrode connects to the second mount electrode near the tip end of the support arm portion and traverses from the mount surface to an opposite surface of the support arm portion via a side surface of the support arm portion and traverses the opposite surface of the support arm portion to connect the second mount electrode to the second excitation electrode.
