Abstract
Provided is a high-performance persistent current switch that is provided with a superconducting coil in which a decrease of a critical current or a critical magnetic field is suppressed. A means for solving the problem is as follows. A persistent current switch provided with a superconducting coil in a switch unit. A superconducting coilincludes a winding portionwhich is formed using a superconductor thin film formed on an outer circumferential face of a base memberThe winding portionincludes a first winding portionand a second winding portionwhich are formed in a double helical shape to be parallel to each other. A terminating end portionof the first winding portionand a starting end portionof the second winding portionwhich are adjacent to each other, are connected to each other.
