Abstract:
A crystal resonator element  2  has excitation electrodes  23 a,  23 b  formed on front and back main surfaces of a crystal resonator plate. Each of the excitation electrodes is made of a ternary alloy containing silver as a major component, a first additive, and a second additive. The first additive is a metal element having a lower sputtering yield than silver and being resistant to corrosion in an etching liquid. The second additive is an element for forming a solid solution with silver. Outer peripheries of the excitation electrodes are first additive-rich regions  9  in which the first additive is rich.

Claim (Index 6):
A method for producing a piezoelectric device, comprising the steps of:\n bonding a piezoelectric resonator element obtained by the production method according to  claim 4  to an inside of a holder; conducting fine adjustment of a frequency of the piezoelectric resonator element by irradiating the excitation electrodes by an ion beam and reducing a mass of the excitation electrodes, and sealing the piezoelectric resonator element hermetically by bonding a lid on the holder.
