Claim 6:
7. A method for manufacturing a smell sensor comprising:
a step of preparing 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 substrate;
a step of disposing, on the sensitive film, a substance adsorption film as the measurement target configured to change the state with adsorption of a smell substance; and
a step of disposing a reference electrode configured to apply a reference voltage to the substance adsorption film to be separated from the sensitive film and not to overlap the sensing section when viewed in a thickness direction of the substrate,
wherein the substance adsorption film is provided to cover the sensitive film and the reference electrode after the reference electrode is disposed.
