INFRARED TEMPERATURE SENSOR

WIPO Patent Application WO/2019/053759

A1

This infrared temperature sensor comprises: a heat conversion film 40 that converts emitted infrared rays to heat; a light-blocking region 28 that is disposed opposite the heat conversion film 40, and that blocks a portion of the heat conversion film 40 from being irradiated with the infrared rays emitted from the object to be detected; an infrared detection element 43 retained in a region on the heat conversion film irradiated by the infrared rays; a temperature compensation element 45 that is retained in a region on the heat conversion film where the infrared rays are blocked by the light-blocking region; a light guide region 27 that guides the infrared rays emitted by the object to be detected to a region where the infrared detection element 43 is disposed; and a shielding body 60 that prevents air from entering from the outside via the light guide region 27 and allows the infrared rays to pass through to the light guide region.
