Assignee: NATIONAL UNIVERSITY CORPORATION TOYOHASHI UNIVERSITY OF TECHNOLOGY
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 15:
16. A smell sensor comprising:
an ion sensor in which at least one 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 substance adsorption film as the measurement target, 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,
wherein 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 substrate,
wherein the ion sensor has a plurality of sensing sections arranged one-dimensionally or two-dimensionally on the substrate, and
wherein a plurality of substance adsorption films are disposed on the sensitive films of different sensing sections.
