Abstract

A magnetic shield panel includes a magnetic shield member made of magnetic material; and a metallic plate or a translucent plate member, wherein the magnetic shield member is attached to the metallic plate or the translucent plate member.

Claims

1. A magnetic shield panel comprising:

a magnetic shield member made of magnetic material; and

a translucent plate member to which the magnetic shield member is attached.

2. A magnetic shield panel according to claim 1, wherein the magnetic shield member is held by a translucent heat insulating member.

3. A magnetic shield panel according to claim 1, wherein a radio wave shield member made of electrically conductive material is attached to the translucent plate member.

4. A magnetic shield panel according to claim 1, wherein the number of the translucent plate member is not less than two.

5. A magnetic shield panel according to claim 1, wherein the magnetic shield member is arranged substantially in parallel with the direction of a magnetic field.

6. A magnetic shield panel according to claim 1, wherein engaging portions are provided at both end portions of the magnetic shield member, and the magnetic shield member is formed into a substantial I-shape or Z-shape.

7. A magnetic shield panel comprising:

a magnetic shield member made of magnetic material; and

a metallic plate to which the magnetic shield member is attached.

8. A magnetic shield panel according to claim 7, wherein the magnetic shield member is held by a heat insulating member.

9. A magnetic shield panel according to claim 8, wherein the heat insulating member is made of refractory material.

10. A magnetic shield panel according to claim 7, wherein the number of the metallic plate is not less than two.

11. A magnetic shield panel according to claim 7, wherein the magnetic shield member is arranged substantially in parallel with the direction of a magnetic field.

12. A magnetic shield panel according to claim 7, wherein engaging portions are provided at both end portions of the magnetic shield member, and the magnetic shield member is formed into a substantial I-shape or Z-shape.

13. A magnetic shield panel according to claim 7, wherein the metallic plate is made of material selected from a group including iron, copper and aluminum.
