Abstract: A humidity detection sensor includes a lower electrode provided on a board, an upper electrode provided so as to face the lower electrode, a humidity sensing film which is formed at least between the lower electrode and the upper electrode and whose dielectric constant changes in response to humidity, and a protective film provided so as to cover the upper electrode. Each of the upper electrode and the protective film has an opening through which the humidity sensing film is partially exposed to the outside. In the opening, the humidity sensing film is provided so as to reach at least a position higher than the position of the lower surface of the protective film.
