Abstract
A crystal oscillator with an improved shock resistance is disclosed. A pair of supporting protuberances protrude within an oscillator main body. A conductive adhesive is spread on the pair of the supporting protuberances, and a quartz blank is bonded to the supporting protuberances across the conductive adhesive. Further, an insulating resin layer is disposed between the quartz blank and a cover so as to elastically press down the conductive adhesive. Further, the length of the connecting parts between the supporting part and the bridge parts is more extended to a certain degree, so that any stress imposed on them can be dispersed.
