PROBLEM TO BE SOLVED: To provide a method for measuring temperature in the tapping gate of a blast furnace for easily, continuously, and accurately measuring the temperature of molten iron flowing out of the tapping gate of the blast furnace. SOLUTION: In the method for measuring temperature in the tapping gate of the blast furnace, radiation temperature measurement is made by using a wavelength band in which the difference of the spectral radiation emissivity between molten iron and molten slug is minimized at a wavelength of 1μm or longer, when measuring the temperature of molten iron flowing out of the tapping gate of the blast furnace, thus acquiring an accurate temperature measurement result even if the temperature of any part of the molten iron and molten slug is measured, continuously measuring the temperature of the molten iron at the tapping gate of the blast furnace without any contact, and accurately grasping the situation of the blast furnace.
