SHEET FOR MAGNETIC PARTICLE INSPECTION, AND MAGNETIC PARTICLE INSPECTION DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a magnetic particle inspection sheet capable of acquiring a clear magnetic particle forming pattern having high detection accuracy even in any case. SOLUTION: This sheet is equipped with a surface material 10 having a light transmission property, a back material 11 at least whose peripheral part is laminated with the surface material 10 so as to specify a closed space M together with the surface material 10, a mixture of magnetic particles 13 and a fluid 14 enclosed in the closed space M, and a space maintaining means provided in the closed space M so that the magnetic particles 13 can be moved in the closed space M. At least either of the surface material 10 and the back material 11 is a sheet for the magnetic particle inspection including a barrier layer 80 for preventing the fluid 14 from being released from the closed space M.
