Abstract
A piezoelectric resonator which can be used as part of a piezoelectric component prevents self-welding of electrodes provided on the surface of a piezoelectric and which include silver with silver coated terminals with which the electrodes abut by forming high fusion point metals on the electrodes. The high fusion point metals include Ni, Cr, W, Ti, Mo, Ni--Cu (monel) or their alloy. The thickness of the high fusion point metal is preferably less than about 1/10 of the thickness of the electrode or less than 1 .mu.m.
