Abstract

PURPOSE:To reduce the fluctuation and dispersion of the frequency as well as to prevent the deterioration of the bonding performance by securing the 3-layer structure for the crystal oscillator and then providing the film to the 2nd layer to prevent diffusion of the 1st and 3rd layers. CONSTITUTION:Metal thin film 6 of Cr, the Cr-Ni alloy and the like featuring a high adhesion property to the crystal is formed on both surfaces of cyrstal oscillator substance such as the AT-cut crystal oscillator or the like, and high-fusion point metal thin film 7 of Ti, Ta, W, Mo, etc. is formed on film 6 to block diffusion of the chrome. Furthermore, film 8 of gold, etc. excellent in the anti-corrosion performance is formed on film 7, with lead wire 9 bonded. As a result, no change is cuased to the film structure in the course of manufacture of the crystal oscillator, thus reducing the fluctuation and dispersion of the frequency. At the same time, the bonding performance is not impaired since no oxide exists on the electrode surface.
