PROBLEM TO BE SOLVED: To provide a method and a device for detecting the deterioration of a wire, capable of detecting semi-disconnection and disconnection occurring in an electric power source code. SOLUTION: An instantaneous value of a cable way current is A/D-converted at a fixed interval of every 100μs (S2) to be sampled, a difference with respect to the last sampling value is computed when an absolute value of the sampled current instantaneous value comes to 1A or less (S3), no current change section is judged to be determined (S4) when the found difference is 0.1 A or less, and the disconnection is determined to occur when the no-current-change sections are detected five times during 8.3 ms of period (S6).
