<p>A superconducting system 1 comprising an electronic device 2 and a thin fiber 3 to electrically connect the electronic device 2 to an external device. By the use of the superconducting system 1, the heat load due to a lead wire can be inhibited, which in turn results in the reduction of the load on a freezer used to cool the electronic device or reduction of the amount of evaporated solvent. It is also capable of coping with the multi-channeling of an electronic device in the future. <IMAGE></p>
