PURPOSE:To obtain a self-recording mark tracing type flaw detector which can perform whole-surface or pitch flaw detection without omission under an unmanned condition when the detector is set to one corner end section of an object to be inspected. CONSTITUTION:In an off-line nondestructive inspection of a flat steel plate, etc., a flaw detector, recorder, and detection sensor which works as a flow detecting sensor, and a detector which detects the leading and trailing edges of the steel plate in the running direction are mounted on a traveling truck 5 mounted with a self-recording marker 2 which marks the surface of the object 1 following the end face of the object 1 which is used as a reference plane of the object 1 and tracer 3 which follows the marker 2. While the truck 5 automatically travels on the surface of the object 1 following the mark of the marker 2, the object 1 is inspected for flaw.
