Abstract
A hydrogen sulfide detection device includes a wire that electrically connects a first node and a second node, and a monitoring circuit that monitors a voltage between the first node and the second node. The wire includes a pattern that is provided on a substrate and is made of a metal that reacts with hydrogen sulfide to corrode, and the pattern includes at least one via. A recessed portion is present in a surface of the substrate, and each of the at least one via is exposed to outside of the substrate through the recessed portion.
Claims5
