Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lightweight magnetic shield system by possessing strength and lightweight against external force, effectively shielding terrestrial magnetism not exceeding 30 micro tesla (μT), attenuating the terrestrial magnetism not exceeding 30 micro tesla (μT) to the minimum 50 dB in particular, and improving mechanical strength and magnetic characteristics of a corner part of a magnetic lamination member. SOLUTION: The magnetic shield system comprises forming a skeleton of a lightweight metal material, demarcating a magnetic shield space by successively overlaying a Co group amorphous alloy thin plate and a resin film and arranging the multiple magnetic lamination material making a multi-layer structure, making a lamination interval of the Co group amorphous alloy thin plate 10-160 μm, making an interval between the magnetic lamination materials 10-200 mm, and having a gentle corner part.
