PROBLEM TO BE SOLVED: To provide a magnetic field leakage prevention structure in which a plurality of shape bodies can be combined with each other by an optimum raw material and optimum arrangement, and an optimum combination can be achieved from a viewpoint of performance, workability, productivity, price or the like.SOLUTION: Disclosed is a magnetic field leakage prevention structure 1 which is formed at a position between a magnetic field generation space E1 and a target space E2, and a magnetic field generated in the magnetic field generation space E1 is prevented from being leaked to the target space E2. This structure includes: a shield material 10 arranged so as to cover at least a part of the target space E2; and a magnetic attenuation material 20 which is arranged in a target area located around the shield material 10 and has a larger magnetic loss than the shield material 10.SELECTED DRAWING: Figure 1 |
