An inspection technique capable of observing a magnetic domain configuration which is formed on a magnetic specimen surface with a higher resolution and at a higher speed as never before. The inspection technique includes an SPLEEM observation unit including a spin polarized electron source, an irradiation optics that projects a spin polarized electron beam that is emitted from the spin polarized electron source to a magnetic specimen having a magnetic domain structure, a stage on which the magnetic specimen is mounted, an imaging optics that focuses and detects the electron beam that is reflected from the magnetic specimen; and cleaning means for cleaning the surface of the magnetic specimen to transfer the magnetic specimen to the SPLEEM observation unit, wherein the magnetic domain structure of the magnetic specimen surface is inspected on the basis of the reflected electron beam.
