<P>PROBLEM TO BE SOLVED: To provide a thermal switch device advantageous for restraining heat intrusion from outside and a superconducting device. Ž<P>SOLUTION: The thermal switch device 400 is provided with a base body 4 forming a heat-insulating room 40, and a first member 500 arranged in the heat-insulating room 40, and a second member 600, arranged in the heat-insulating room 40 with at least a part formed of a base material having a higher coefficient of thermal expansion than the first member 500. Accordingly, as the second member 600 is cooled, a mode is changed into a first one in which a contact degree of the first member 500 and the second member 600 gets higher, directly or indirectly. As a temperature of the second member 600 is raised, the mode is changed into a second one in which a contact degree of the first member 500 and the second member 600 becomes, directly or non-directly, lower or becomes non-contacting.
