<P>PROBLEM TO BE SOLVED: To restrain lift-off noise from being generated even when an unevenness exists on a surface of an inspected object, in non-contact inspection using a multi-coil for eddy current flaw detection. Ž<P>SOLUTION: The multi-coil probe for eddy current flaw detection includes a frame, a plurality of coils for eddy current flaw detection provided on the frame so as to advance and retreat in a direction of the inspected object, and a plurality of protrusions integrated with the coils and arranged on a side of the coils for eddy current flaw direction facing the inspected object.
