Abstract
A surface mount type quartz crystal device according to a first aspect of the disclosure includes a ceramic package, a pedestal blank, a quartz-crystal vibrating piece. The pedestal blank is placed within the ceramic package via a conductive adhesive. The quartz-crystal vibrating piece is placed on the pedestal blank. The conductive adhesive is formed along an outer peripheral side of the pedestal blank so as to avoid overlap with the excitation electrode viewed in a normal direction of the excitation electrode. The pedestal blank is formed to avoid a region where a distance from the quartz-crystal vibrating piece is equal to or smaller than a size of a clearance between the pedestal blank and the quartz-crystal vibrating piece at the outer peripheral side, in a region where the excitation electrode faces at the pedestal blank side viewed in the normal direction.
