PROBLEM TO BE SOLVED: To provide an ultrasonic testing device which performs accurate ultrasonic testing.SOLUTION: An ultrasonic testing device 10 includes an ultrasonic contact 12 which emits an ultrasonic wave U, and a receiver 13 which detects echo N, S of the ultrasonic wave U emitted by the ultrasonic contact 12, to perform ultrasonic testing on a joined body W formed by joining first and second members Wa, W2 different in acoustic impedance. A heater 14 is provided which heats the first member W1 when the ultrasonic wave U is made incident on the joined body W by the ultrasonic contact 12. |
