| description | PROBLEM TO BE SOLVED: To provide an ultrasonic transducer that allows widening the frequency bandwidth capable of performing impedance matching.SOLUTION: An ultrasonic transducer 100 includes: a piezoelectric element 1 that generates an ultrasonic wave, receives a reflection wave from a test object, and outputs the reflection wave; and a resistive element 2, a resistive element 3, and an inductor 4 that are connected to the piezoelectric element 1. A constant resistance circuit is constituted from the piezoelectric element 1, the resistive element 2, the resistive element 3, and the inductor 4.
