Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for an eddy current flaw detection by which flaw inspection of a thick plate of a structure such as an atomic power plant and an aircraft can be executed, and detection of flaws not only on the surface but also on a rear face opposite to the inside and a flaw detection face can be executed, and a flaw detection probe which is optimum therefor. SOLUTION: The method for the eddy current flaw detection is characterized in that oppositely directed currents are fed to two excitation coils, the eddy currents of the respective coils are overlapped in a region between the excitation coils, and the flaw detection is executed by a detection coil arranged between the excitation coils.
