Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for effectively inspecting the state of removing a fusing slag on the outer peripheral surface of a stent and its device. SOLUTION: In a method for inspecting a state of removing a fusing slag in a cylindrical stent 1 passing a step of removing the fusing slag created by a laser processing, there is provided a CCD camera 2 which rotatably supports the stent 1 by a horizontal state, and is connected to a computer 5 via an image processor 4, perpendicular to the axial line of the stenter 1, and the stent 1 is rotated at a prescribed angle, and an upper end part and a lower end part of a stent surface are fetched with band-like images, and in comparison with a permitted value of the fusing slag set previously, and a quality decision of the state of removing the fusing slag is made.
