PROBLEM TO BE SOLVED: To provide an eddy current flaw detection probe for a pulsed eddy current flaw detector inspecting magnetic materials, such as carbon steel, capable of detecting defects inherent in an inspection object at a high resolution, while maintaining defect detection sensitivity. SOLUTION: The eddy current flaw detection probe reduces an eddy current generation range, by arranging the magnetic materials around an exciting coil which prevent a diffusion of a generating magnetic field, restrains a range of an eddy current to be generated in the inspection object by disposing conductive non-magnetic materials on the outer circumference of the magnetic materials and near the inspection object; maintains the generating magnetic field; and enables pulsed eddy current flaw detection, to enhance resolution by lessening the generation range of the eddy current.
