Liquid ejecting head and liquid ejecting apparatus

Abstract

Provided is a liquid ejecting head including a plurality of substrates that are at least partially bonded to one another with adhesives and form a liquid passage in which a liquid flows. The liquid passage includes a pressure-generating chamber that communicates to a nozzle opening through which the liquid is ejected. The adhesive being exposed to a wall surface of the passage on the upstream side of the pressure-generating chamber is composed of a first adhesive, and the adhesive being exposed to a wall surface of the downstream-side passage including the pressure-generating chamber is composed of a second adhesive. The second adhesive has affinity with the liquid higher than that of the first adhesive.

Dependencies are inferred from the claim text.
