Claim Text:
1. A piezoelectric vibrator having a piezoelectric vibrating reed mounted on a substrate through a conductive adhesive, the piezoelectric vibrating reed comprising: a pair of vibrating arms extending along a first direction and arranged side by side in a second direction perpendicular to the first direction; a base supporting the pair of vibrating arms; and a pair of support arms positioned on an outer side of the pair of vibrating arms in the second direction, the pair of support arms bonded to the substrate, wherein the conductive adhesive extends along an inner sidewall of the support arms and along an outer sidewall of the support arms, and wherein an extrusion amount of the conductive adhesive on the inner sidewall of the support arms is smaller than an extrusion amount of the conductive adhesive on the outer sidewall of the support arms in bonded portions between the support arms and the substrate.
