Abstract
A corrosive environment monitoring device that suppresses a decline in measurement precision in an initial period of monitoring the corrosivity of an environment and measures the corrosivity of the environment continuously and with high precision over a long period of time. The corrosive environment monitoring device includes: a layered body having an insulating plate, a base metal thin film that is formed on the insulating plate and is corrosion resistant with respect to a corrosive substance, and a sensing metal thin film that is formed on the base metal thin film and is corrosion susceptible with respect to the corrosive substance; and a housing that encloses the layered body, has an opening oriented in a side face direction, and forms a gas passage inside for the corrosive substance, wherein the sensing metal thin film is formed in a limited region on the base metal thin film.
