To provide a deterioration diagnostic system and a deterioration diagnostic method of a wire which can diagnose a deterioration state of the wire such as a contact wire, a messenger wire or a feeder using thermography.SOLUTION: A deterioration diagnostic system comprises: infrared imaging means 12A, 12B, 12C which are installed so that imaging a part of a wire 10 as an object to be diagnosed can be performed; a storage device 21 which stores image data obtained from the imaging performed by the infrared imaging means; and a deterioration diagnostic device 20 which analyzes the stored image data to determine a deterioration state of the wire 10. The deterioration diagnostic device 20 comprises: vehicle information acquisition means which acquires information about a run of a vehicle in a section where the wire 10 as the object to be diagnosed is laid; command output means which calculates a timing at which an electric current flows through the wire as the object to be diagnosed on the basis of the information acquired by the vehicle information acquisition means, to generate and output an imaging command to the infrared imaging means; and deterioration determination means which analyzes the image data obtained from the imaging performed by the infrared imaging means to determine the deterioration state.SELECTED DRAWING: Figure 1
