PROBLEM TO BE SOLVED: To provide an eddy current flaw detector, capable of simply and efficiently performing the flaw detection work of pipings having a bent part, such as an elbow or the like, having high accuracy, and being relatively simple in constitution and capable of being reduced in cost and inspection cost. SOLUTION: This eddy current flaw detector 1 for the bent pipe is equipped with a plurality of segments 4 connected by a connection part 2, capable of permitting operation over a definite angle range and directionally varied along the outer surface of the elbow 3 to be subjected to flaw detection, the eddy current probe 5 provided at least to either one of the segments 4 and inspecting the crack of the elbow 3, on the basis of an eddy current and the wheels 6 provided at least to the segments 4a and 4b, arranged at both ends of the segments 4 and coming into contact with the outer surface of the elbow 3 capable of rotation and running.
