PROBLEM TO BE SOLVED: To provide a flaw inspection method for a strip-like material which observes the flaw of the strip-like material detected during feed without stopping the feed of the strip-like material, and a flaw inspection device therefor. SOLUTION: The flaw inspection device is equipped with a flaw detecting part 11 for detecting the flaw of a continuously fed strip-like material 15 to acquire the position data of the flaw on the strip-like material 15, a flaw observing part 13 which is arranged on the downstream side of the strip-like material 15 of the flaw detecting part 11 and stops the flow part detected by the flaw detecting part 11 of the strip-like material 15 to observe the same and a transfer speed converting part 12 which is arranged between the flaw detecting part 11 and the flaw observing part 13 with respect to the feed direction of the strip-like material 15 and extends the length of the feed route of the strip-like material 15 fed from the upstream side in a freely extensible and contractable manner to reconcile the detection of the flaw while feeding the strip-like material 15 in the flaw detection part 11 and the observation of the flaw in such a state that the strip-like material 15 in the flaw observing part 13 is stopped.
