ABSTRACT:
A non-destructive inspection device (X1) includes an exciting pole (10) having a magnetic flux exciting surface (11) for exciting a magnetic flux to form a magnetic field in an inspection target, a recovering pole (30) having a magnetic flux recovering surface (31) for recovering the magnetic flux excited from the magnetic flux exciting surface (11), and a coil array (50) having a plurality of loop coils though which the magnetic flux excited from the magnetic flux exciting surface (11) passes prior to reaching the inspection target, the coil array being offset toward the recovering pole (30) with respect to the magnetic flux exciting surface (11).
