PROBLEM TO BE SOLVED: To provide a device and method for detecting disconnection of a wire that is applicable not only to a wire in non-use but also to a wire in use and can accurately detect the disconnection. SOLUTION: This disconnection detecting device comprises a high-frequency pulse signal input section 100 for inputting a high-frequency pulse signal to a fixed cable 22a, among fixed cables 22a and 22b and a moving cable 24 with a predetermined length interconnected in series, a signal waveform measuring section 102 for measuring a reflected waveform of current flowing in the fixed cables 22a and 22b and moving cable 24 with the input signal from the high-frequency pulse signal input section 100, and a determining section 103 for determining the existence of the reflected waveform measured by the signal waveform measuring section 102 in a wire to be detected.
