PROBLEM TO BE SOLVED: To provide a technology relevant to a current switch which carries out the switching of a permanent current flowing in a supercouductive coil forming high magnetic field, where there is no need to apply ultra high voltage in the manufacturing process for constituting a structure in which voids are hard to remain inside. SOLUTION: The permanent current switch includes a superconductive element wire (31) wound around a bobbin body (20) while being connected to a superconductor, a heater wire (32) which switches the superconductive state/normal conducting state by heating the superconductive element wire (31), a partition wall (33, 34) having a plurality of pores (33h) prepared in the interlayer of the superconductive element wire (31) or the heater wire (32), and a fixing layer (38) which impregnates into a gap between the pores (33h) as well as the superconductive element wire (31) and the heater wire (32) and fixes them.
