PROBLEM TO BE SOLVED: To provide a fault detecting apparatus for a wire for accurately and easily detecting a fault on a surface of the various wire on line at the time of manufacturing the wire. SOLUTION: The fault detecting apparatus comprises an ultrasonic probe 1 disposed near a surface of a wire 2 to oscillate ultrasonic wave toward the wire 2 to receive reflected wave and to convert it into an electric signal, a pulse transmitter-receiver 3 for transmitting an electric signal for oscillating the wave at the probe 1 and receiving an electric signal of the reflected wave of the wave converted by the probe 1, and a fault detector 4 for deciding presence or absence of a fault from the signal of the reflected wave of the wave received by the transmitter-receiver 3. |
