PROBLEM TO BE SOLVED: To suppress as much as possible deterioration in magnetic shield performance of a magnetic shield device formed by mutually joining a group of relatively thick magnetic bodies to a group of relatively thin magnetic bodies. SOLUTION: The magnetic shield device is such that an end of a longitudinal direction of a first shield member 31 protrudes while having the thickness same as those of second and third shield members 32, 33. The tip surface of a protruding portion of the first shield member 31 is made to abut to the tip surface of a longitudinal direction of the second and third shield members 32, 33. Furthermore, fourth-seventh shield members 34-37 each having a shape matching the region except the region where the second and third shield members 32, 33 are disposed, of the region of the first shield member 31 which does not protrude, are disposed on regions below and under the protruding portion of the first shield member 31.
