Claims

[Scope of utility model registration request]

A terminal plate is fixed to the open end of an aluminum case with a piezoelectric element attached to the inner end surface, one terminal attached to the terminal plate is connected to the piezoelectric element with a lead wire, and the other terminal is electrically connected to the aluminum case. In a sound wave transducer, a sound absorbing material is pasted on the inner surface of a terminal plate, a through hole is provided in the center of the terminal plate and the sound absorbing material, and a bare thin wire is used as the lead wire connected to the compression element. An ultrasonic transducer characterized in that the ultrasonic transducer is inserted through a through hole and connected to a single terminal on the outside of the terminal board.
