Abstract
Since, due to heat flowing from the outside through central conductors of cables or connectors into an electronic circuit that is operated in a state of being cooled to a low temperature, a temperature distribution or local temperature rising occurs in the electronic circuit, a desired characteristic cannot be obtained for the electronic circuit. There is disclosed an electronic apparatus comprising an electronic device accommodated in a vacuum heat insulation housing, provided with an electronic circuit which is cooled to a temperature between 4 K. and 150 K. to operate, and an input/output coaxial connector of which central conductor is hold by a dielectric having a heat conductivity of 10 W/m.multidot.K. or more at the temperature between 4 K. and 150 K.; and cooling means accommodated in the vacuum heat insulation housing, for cooling the electronic device to the temperature between 4 K. and 150 K via a cooling introduction member connected with the input/output coaxial connector, wherein the electronic device is mounted in a state of being separated from the cooling means. Since the problem of heat flow from the outside into the electronic circuit is eliminated, the electronic circuit is stably operated.
