Abstract

PURPOSE:To inexpensively form a product having a stable characteristic similar to gold by using a solder layer as the uppermost layer of the electrode of a piezoelectric element part of an ultrasonic delay line. CONSTITUTION:The solder layer is used as an uppermost layer 4 of an electrode 1 of the ultrasonic delay line, and a layer 3 consisting of chromium and a solder and a chromium layer 2 are laminated under this layer 4, and they are adhered to a piezoelectric element part 5. The electrode 1 is laminated on an ultrasonic delay line 10 with the piezoelectric element part 6 between them. Thus, the stable product similar to a product using gold is inexpensively formed.
