A metal body monitoring apparatus has a magnetic detection device, a distance detection device, and a processing device. The magnetic detection device has a magnetic sensor unit, and the magnetic sensor unit is provided on a moving body that relatively moves over a metal body, and detects a generated leakage magnetic field in a non-contact manner. The distance detection device is provided on the moving body and detects a movement distance relative to the metal body of the moving body. The processing device converts first data representing the time-series of the detection signal strength from the magnetic detection device into second data representing a relationship between the movement distance and the detection signal strength based on the movement distance at each time point detected by the distance detection device. The processing device extracts a spectral response in a wave number space specified from the second data, and outputs monitoring information which is information based on the extracted spectral response.
