PROBLEM TO BE SOLVED: To provide a crystal device, which will not degrade conductivity due to silicon conductivity adhesive member at a junction section with a base substrate and simultaneously obtains stable, proper electrical characteristics even in excitation electrodes. SOLUTION: After drawer electrodes and exciting electrodes are formed at a crystal vibrator 3, at least only extraction electrodes 32 and 34 of the lower surface side are heated locally by hot-blast radiation or heater heating, and metal in a surface metal layer is deposited at the surface of an AU layer as a surface deposit layer, then it is accommodated and held for curing, at the lower surface of the base substrate using silicon conductivity adhesive.
