PROBLEM TO BE SOLVED: To provide a two-dimensional radiation thermometer that can more smoothly display a two-dimensional temperature distribution on a displaying section. SOLUTION: This two-dimensional radiation thermometer is provided with a temperature detecting section 2 which detects the temperature of each corresponding area, and a display control unit which causes the temperature distribution in a measuring area to be displayed based on the temperature of each corresponding area. The temperature detecting section 2 is provided with an optical system 2b which distributes incident light in a plurality of directions and sensor arrays 22a-22c, each of which is constituted of a plurality of non-contacting temperature detecting sensors. Each sensor array can receive each incident light and, in addition, is arranged so that part of the corresponding area of each non-contacting temperature detecting sensor in one sensor array may overlap part of the corresponding area of each non-contacting temperature detecting sensor array in the other sensor arrays. The display control unit causes temperature distribution to be displayed based on the temperatures of the overlapping parts of the corresponding areas calculated by performing interpolation by using the signals SAij-SCij of the sensors of the sensor arrays 22a-22c.
