Ultrasonic transmitting/receiving device and method for fabricating the same |
摘要 |
An ultrasonic transmitting/receiving device that effectively suppresses ringing during emission of ultrasonic waves and improves time resolution when measuring a sonic velocity includes a pair of ultrasonic transducers. Each of the ultrasonic transducers has a piezoelectric vibrator including a first electrode and a second electrode that are separated by a piezoelectric body and a backing disposed in contact with the first electrode and composed of the same material as a material of the piezoelectric body. The ultrasonic transducers are connected by a support so as to face each other and have a substantially rectangular U-shape as a whole when viewed from the side.
