PROBLEM TO BE SOLVED: To provide a temperature estimation device of an automatic vending machine for precisely estimating characteristics of a merchandise temperature in a short period of time in the cooling/heating time of the automatic vending machine, and for issuing warning in the middle of the measurement time when any problem is caused. SOLUTION: This temperature estimation device of an automatic vending machine is provided with a temperature data storage part 14 for storing temperature data measured from a plurality of merchandise of an automatic vending machine, a standard temperature differential coefficient data part 13 for preliminarily storing the temperature data as standard temperature data, a differential coefficient calculating part 15 for calculating the differential coefficient of the measured temperature and a differential coefficient comparing part 16 for comparing the standard differential coefficient with the differential coefficient of the measured temperature, and configured to perform control to issue warning when the differential coefficient compared by a warning issue processing part 17 is turned to be beyond a proper range in the middle of a cooling/heating test.
