Abstract:
1. An eddy current flaw detection probe having a flexible substrate, which faces the surface of an inspection target, and a plurality of coils, which are fastened to the flexible substrate and sequentially selectable, the eddy current flaw detection probe comprising: a first elastic body which is positioned opposite the inspection target for the eddy current flaw detection probe, the first elastic body having an elastic coefficient that varies in a longitudinal direction; a second elastic body which is a porous body positioned between the flexible substrate and the first elastic body; and pressure means for pressing the first and second elastic bodies against the inspection target; wherein the pressure means includes a mechanism configured to rotatably support the first elastic body, including two or more elastic plates comprising the first elastic body, for rotation about an axis of rotation that is orthogonal to a longitudinal dimension of the first elastic body.
