PROBLEM TO BE SOLVED: To provide a method for processing eddy current flaw detection signal, capable of automatically identifying defective sections and accurately restoring the shape of defects. SOLUTION: The method for processing eddy current flaw detection signal is used for a nondestructive inspection and comprises a step of computing a discrimination boundary for identifying the defective section and a non-defective section, based on data of the defective section and the non-defective section derived from the vector data of a multidimensional space, consisting of eddy current flaw detection signals at respective flaw detection positions in the object to be inspected; and a step of projecting the vector data on a normal vector perpendicular to the discrimination boundary, converting them into amplitude values for respective flaw detection positions and determining the region as the defective section, having value that is equal to or larger than the prescribed threshold.
