Title:
INFRARED DETECTOR, AND GAS SENSOR PROVIDED WITH INFRARED DETECTOR
Document Type and Number:
WIPO Patent Application WO/2022/176949
Kind Code:
A1
Abstract:
An infrared detector 1 according to the present invention is provided with a substrate 2, an infrared light absorbent body 3 which is provided on the substrate 2 and which absorbs infrared light and emits heat, and a thermoelectric conversion layer 4 which is provided between the substrate 2 and the infrared light absorbent body 3, and which converts the heat from the infrared light absorbent body into an electrical quantity, characterized in that the infrared detector 1 is additionally provided with: a heat conduction suppressing layer 5 which is provided between the substrate 2 and the thermoelectric conversion layer 4, and which suppresses heat conduction between the substrate 2 and the thermoelectric conversion layer 4; and an insulating layer 6 which is provided between the thermoelectric conversion layer 4 and the infrared light absorbent body 3, and which electrically insulates the thermoelectric conversion layer 4 and the infrared light absorbent body 3 from one another. The gas sensor of the present invention is characterized by being provided with the infrared detector 1.
