An inspection device that is capable of inspecting all heat-transfer-tube sealing portions in a steam generator and that is also capable of analyzing a defect shape is provided. An inspection device that employs the eddy-current flaw detection method to inspect the presence/absence of a defect in a welded portion (103) between a tube (101) and a tube plate (102) is provided with a main unit (41) that has a circular-column portion (41A), which is inserted into the tube (101), and a flange portion (41B), which is pressed against the tube plate (102), and that is rotatable with respect to the welded portion (103); a probe (42) that is disposed inside the main unit (41), that can be moved close to and away from the welded portion (103), and that detects a defect in the welded portion (103); and a pressing portion (44) that presses the probe (42) toward the welded portion. |
