An electronic device includes a base material, a first metal film disposed on the base material and containing nitrogen and chromium, and a second metal film disposed on the first metal film and containing gold. In the first metal film, the number of nitrogen atoms may be between 20% to 100% of the number of chromium atoms. Further, the distribution of nitrogen atoms in the first metal film is larger in a third region sandwiched between a first region on the base material side of the first metal film and a second region on the second metal film side than in the first region and in the second region.

The liquid ejecting head includes a nozzle plate in which nozzle holes which are through holes are formed, and ejects liquid from the nozzle holes. The nozzle hole has a first nozzle portion which is opened to an ejection surface to which liquid is ejected from nozzles of the nozzle plate, and a second nozzle portion which communicates with the first nozzle portion, and is opened to a surface opposite to the ejection surface of the nozzle plate, and of which the opening diameter is larger than the opening diameter in the ejection surface of the first nozzle portion. The first nozzle portion is covered with a liquid repellent film which has higher liquid repellency than a base material of the nozzle plate and an inner wall of the second nozzle portion is provided with a region which has lower liquid repellency than the liquid repellent film.
