Abstract: A piezoelectric device includes a crystal element, excitation electrodes, extraction electrodes, a base, and first and second wiring electrodes on the base and connected to the extraction electrodes. The crystal element is connectedly secured to the first wiring electrode with conductive adhesive at an end part at a side of the one side on one surface of the crystal element. The fixing and the wire bonding are performed such that a secured position with the conductive adhesive overlaps a bonding position on the crystal element side by the wire bonding in a crystal element thickness direction. The first wiring electrode is disposed at an end part at a side of one side of the base and has a planar shape and a size so as to planarly encompass at least a region formed by projecting a part where the conductive adhesive contacts the crystal element to the base side.
