Abstract:
1. A thermometer comprising: a first surface temperature measurement unit configured to measure a surface temperature of a measurement subject as a first surface temperature; a first reference temperature measurement unit configured to measure a temperature at an opposite side of the first surface temperature measurement unit as a first reference temperature through a first heat insulating portion having a first thermal resistance value; a second surface temperature measurement unit configured to measure a surface temperature of the measurement subject at a position different from the first surface temperature measurement unit as a second surface temperature; a second reference temperature measurement unit configured to measure a temperature at an opposite side of the second surface temperature measurement unit as a second reference temperature through a second heat insulating portion having a second thermal resistance value; a storage unit configured to store the first surface temperature and the first reference temperature; a temperature correction unit configured to correct the first surface temperature and the first reference temperature stored in the storage unit based on the second surface temperature and the second reference temperature in a case in which the first thermal resistance value and the second thermal resistance value are different from each other; and a temperature calculation unit configured to calculate a core temperature of the measurement subject using the first surface temperature and the first reference temperature which have been corrected.
