Patent ID: 8531185

Claim:
A magnetic shield body configured to be arranged on at least a part of a wall that partitions a magnetic field generation source from outside such that magnetism generated by the magnetic field generation source can be at least partially shielded not to leak to the outside beyond the wall, comprising: a plurality of cylindrical body unit; and a supporting unit configured to support the plurality of the cylindrical body units, wherein each of the cylindrical body unit includes a plurality of cylindrical bodies having permeability, a cross-sectional shape of a cross section orthogonal to axial direction of each of the cylindrical bodies of each of the plurality of the cylindrical body unit is the same each other, the cylindrical bodies of each of the plurality of the cylindrical body unit are arranged such that central axes of the cylindrical bodies coincide with each other and side surfaces of the cylindrical bodies form a mutually same plane, the cylindrical bodies of each of the plurality of the cylindrical body unit are arranged with a mutual interval between the cylindrical bodies such that a magnetic resistance between the cylindrical bodies can be increased, and the supporting unit supports the plurality of the cylindrical body units such that side surfaces of the cylindrical bodies of the cylindrical body units face each other with a mutual interval.
