PROBLEM TO BE SOLVED: To provide a compact and lightweight magnetic mine sweeping device easy to handle, capable of securing a simulated magnetic flux range as wide as possible and of reducing electric power provided from outside. SOLUTION: This device consists of a refrigerating machine direct cooling style superconductive coil part 11 in which a cooling part of a gas circulation type heat accumulator style refrigerating machine 14 is mechanically contacted on a coil main body 15 made from a superconductive material wound up in a coil like shape through a heat conduction plate, a cooling part 12 radiating heat by taking heat generated from the refrigerating machine 14 in a heat radiator 17 through cooling water as the medium, and an electric power source control part 13 supplying electric power to the superconductive coil part 11 and the electric power source control part 13. Those components are loaded on a towed body and are towed by a ship or a helicopter. Magnetic mines are sympathetically detonated by magnetic flux generated from the superconductive coil part 11.
