Abstract: To provide an infrared temperature sensor that is corrected in detected temperature while ensuring high responsiveness. An infrared temperature sensor 10 according to the present invention includes a heat conversion film 40, an infrared detection element 43 held by the heat conversion film 40, a temperature compensation element 45 that is provided adjacently to the infrared detection element 43 and is held by the heat conversion film 40, a light guide part 59 that guides entered infrared rays toward the infrared detection element 43, and a blocking part 27 that blocks the infrared rays from being incident on the temperature compensation element 45, in which an inner surface of the light guide part 59 configures an irradiation surface 57 to be irradiated with the infrared rays, and the irradiation surface 57 includes a correction region 58 that is different in emissivity of the infrared rays from surroundings.
