Claims (1)

[Scope of utility model registration request] In an ultrasonic transducer comprising a substrate, a pair of lead terminal plates attached to the substrate, and a piezoelectric flexure vibrator supported by the lead terminal plates, each of the lead terminal plates is embedded in the substrate. The pair of lead terminal plates are made of an elastic metal material and have a terminal rod portion and a frame portion provided at the upper end thereof, and the frame portions of the pair of lead terminal plates face each other, and
Each of the tongues is provided with tongues extending in mutual directions, and the tongues are soldered to the electrodes on both sides of the piezoelectric flexural vibrator at their vibration nodes, thereby supporting and leading the piezoelectric vibrator. An ultrasonic transducer characterized in that electrical connection to a terminal can be achieved at the same time.
