Claims

[Scope of utility model registration request]

In an ultrasonic vibrator consisting of a piezoelectric element with a predetermined thickness, electrode surfaces formed on both sides of the piezoelectric element, and lead wires fixed to each electrode surface, a portion of a peripheral corner of the piezoelectric element At the same time, the ends of each of the electrode surfaces are extended to the other electrode surface side so as to surround the cut out portion of the corner portion, thereby forming a folded electrode portion. An ultrasonic transducer characterized in that each of the lead wires is fixed to a side end surface of the piezoelectric element related to the folded electrode section.
