Abstract: An inspection device (12) for a cold insulator (10) includes: an RF reader 50 that receives from an RF tag 30 a detected temperature of a cold insulator in a cold insulation box, the detected temperature being detected by a temperature sensor (20) attached to a surface of the cold insulator; and a controller 61. The controller outputs information indicating a result of comparison between: at least one of a lower limit temperature obtained by adding a predetermined first value to a lowest management temperature of an article that is kept cold in the cold insulation box and an upper limit temperature obtained by subtracting a predetermined second value from a solidification temperature of the cold insulator; and the detected temperature of the cold insulator which has been received by the RF reader.
