PROBLEM TO BE SOLVED: To provide a crystal device for surface mounting which maintain good impact resistance. SOLUTION: In the crystal device, both sides at one end of a crystal chip 2 in which a lead-out electrode extends from an excitation electrode are fixed to a crystal terminal 3 provided on both sides at one end on an inner bottom surface of a mounting substrate using a conductive adhesive 7. The crystal terminal 3 provided on both sides at one end includes an area with the small thickness closer to the center and an area with the large thickness closer to the outside, while both facing each other.
