1. A magnetic structure comprising:
a magnetocaloric material that changes in temperature due to application and removal of a magnetic field; and
a high heat conduction member that is in contact with the magnetocaloric material and has higher heat conductivity than the magnetocaloric material;
a high heat conduction wall in contact with each end portion of at least one of the magnetocaloric material and the high heat conduction member;
a heat insulation material covering outer surfaces of the magnetic structure other than a surface that transmits heat to another member among the outer surfaces of the magnetic structure; and
a casing further covering the heat insulation material,
wherein the magnetocaloric material includes a plurality of hexagonal columns, the high heat conduction member has a honeycomb structure, and hexagonal holes of the honeycomb structure are filled with the magnetocaloric material, and
wherein the high heat conduction wall has a higher heat conductivity than the magnetocaloric material.
