Abstract
In order to provide a moisture detection element, a gas detection device, and a breath inspection system that are compact and have high response performance, the moisture detection element includes an insulating section made of an insulating material, an application electrode to which an voltage is applied, and a detection electrode that detects a voltage signal corresponding to a current flowing through an electrical path via water molecules adsorbed on the insulating section by the voltage applied to the application electrode.
