PROBLEM TO BE SOLVED: To easy to inspect the bad state of an inspection target having a curved surface on which the joined part of first and second members is formed. SOLUTION: This joined sintered object inspection device 20 is constituted so that a joined sintered object 40 having the curved surface, on which the mutually joined part 44 of main body members 42 is formed, is irradiated with the light polarized by a first polarization plate 32 and the light incident through the curved surface of the jointed sintered object 40 is polarized by a second polarization plate 34 to be detected by a camera 35. By polarizing the irradiated light to apply the same to the jointed sintered object 40 and further polarizing the light transmitted through the joined sintered object 40 to be scattered to detect the camera it can be suppressed that the peripheral edge of the photographed image becomes dark by the light passed through the curved surface. Accordingly, the wider range of the jointed sintered object 40 can be inspected. COPYRIGHT: (C)2009,JPO&INPIT
