Claims

[Scope of utility model registration request]

One electrode film of the piezoelectric element, in which electrode films are formed on both surfaces of the piezoelectric plate, is bonded to the bottom of a metal case with an opening at one end, and a lead terminal is fixed to a terminal plate fixed to the opening. This is an ultrasonic transducer in which one of the lead terminals is electrically connected to the other electrode film of the piezoelectric element, and another lead terminal is electrically connected to the metal case, and the other lead terminal is made of conductive metal. The connection plate is inserted through a hole provided at one end of the connection plate and is electrically conductively connected to the connection plate, and the other end of the connection plate is electrically conductively connected to the inner wall of the metal case. Ultrasonic transducer.
