Abstract
A smell sensor includes an ion sensor in which a sensing section provided with a sensitive film configured to change a potential in accordance with a state of a measurement target is formed on a semiconductor substrate; a substance adsorption film disposed on the sensitive film and configured to change the state with adsorption of a smell substance; and a reference electrode configured to apply a reference voltage to the substance adsorption film. The reference electrode is disposed to be separated from the sensitive film and not to overlap the sensing section when viewed in a thickness direction of the semiconductor substrate.
