Temperature estimation system, temperature estimation method, and recording medium storing temperature estimation program

A computer readable recording medium storing a temperature estimation program that causes a computer to function as:

• an internal temperature data obtainer that obtains internal temperature data of a user mobile terminal device carried by a user;
• an operation data obtainer that obtains operation data on an operation state of the user mobile terminal device;
• and
• a temperature estimator that calculates an estimated value of an external temperature in a vicinity of the user mobile terminal device from the internal temperature data and the operation data of the user mobile terminal device, based on correlation among internal temperature data of a mobile terminal device for measurement, operation data on an operation state of the mobile terminal device for measurement, and actual temperature data that represents an actual environmental temperature in a vicinity of the mobile terminal device for measurement.
