Abstract
A superconducting switch is provided in which the structural strength of the superconducting switch is kept, and thermal efficiency between a superconducting film and a heater is high when an ON state (superconducting state) and an OFF state (normal conducting state) of the superconducting switch are switched. The superconducting switch includes a substrate, a heater for generating heat by energization, a conductive film, and a MgBfilm evaporated on the conductive film. The heater, the conductive film and the MgBfilm are laminated in this order on one surface of the substrate.
