摘要： PROBLEM TO BE SOLVED: To accurately detect the presence or absence of corrosion in a linear object and a corrosive section. SOLUTION: Magnetization equipment 10, including a magnetization coil C, is provided so that one portion of the target linear body 2 whose corrosion section should be detected is surrounded. The magnetization equipment 10 is moved at a constant speed along the target linear body 2; at the same time, a magnetization current is allowed to flow into the magnetization coil C for magnetizing the target linear body 2; the strength of magnetization for magnetizing the target linear body 2 is measured continuously, the amount of magnetic flux passing through the inside of the magnetized target linear body 2 is measured continuously, and the amount of travel in the magnetization equipment is measured; the relation between the strength of a magnetic field and the amount of magnetic flux in a reference linear body is measured; and then, based on the strength of the measured magnetic field and the above relation on the target linear body 2, a corrected amount of magnetic flux on the target linear body 2 is calculated. Based on the difference between the measured amount of magnetic flux at the starting position of continuous measurement and the measured amount of magnetic flux at the end point and then the measuring position, the amount of magnetic flux at the measuring position is subjected to drift correction.
