Abstract
A substance detection sensor includes an insulating layer; two electrodes spaced in opposed relation to each other on the insulating layer; and conductive layers formed between the two electrodes on the insulating layer so as to electrically connect the two electrodes, and of which a swelling ratio varies depending on the type and/or amount of a specific gas. The conductive layers are formed by dividing into plural layers between the two electrodes.
