Abstract
The invention relates to a liquid nitrogen cooling sensor device container and liquid nitrogen cooling sensor equipment, and effectively reduces low-frequency noise while maintaining the ease with which a probe can be inserted in and removed from liquid nitrogen. Said invention comprises: a liquid nitrogen containing insulating container that contains liquid nitrogen; a sensor fixing member which has a distal end portion to which a sensor operating at a temperature of the liquid nitrogen is attached; and a fixing buffer member which is for fixing the sensor fixing member to the liquid nitrogen containing insulating container, wherein the fixing buffer member exerts a buffering effect in the liquid nitrogen.
