SURFACE-MOUNTED CRYSTAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a surface-mounted crystal device of which DLD (Drive Level Dependence) property is improved by preventing blank chips from being deposited to a crystal vibration piece.SOLUTION: A surface-mounted crystal device (600) comprises: a ceramic package (630); a rectangular pedestal blank (120) which is formed from a crystal material and mounted within the ceramic package via a conductive adhesive (161); and a crystal vibration piece (110) which is formed in a rectangular shape having a longer side and a shorter side and mounted on the pedestal blank while forming a pair of excitation electrodes (111) and a pair of lead-out electrodes (112) which are led out to one end in a direction where the longer side extends from the pair of excitation electrodes. The conductive adhesive is formed in a normal direction of the excitation electrodes so as not to be overlapped with the excitation electrodes. A length of the pedestal blank in the direction where the longer side extends is shorter than a length of the crystal vibration piece in a direction where a longer side extends, and the pedestal blank and the excitation electrodes are not overlapped in a view in the normal direction of the excitation electrodes.
