PROBLEM TO BE SOLVED: To provide a method for presuming temperature of a material to be heated with which the temperature of the material in a heating furnace can surely be presumed for a long term. SOLUTION: The method for presuming the temperature of the material to be heated in the heating furnace, includes a step for measuring the gas temperature in the furnace by detecting heat-radiation energy in an absorbing wave length zone of a specific gas component existing in the furnace, a step for measuring the surface temperature of the furnace inner wall, a step for calculating heat input which calculates the heat input into the material from the gas temperature in the furnace, the surface temperature of the furnace inner wall measured with the step for measuring the furnace wall temperature and the presumed temperature of the material before a prescribed time, and a step for presuming the temperature which presumes the temperature of the material from the heat input calculated with the step for calculating the heat input.
