Patent ID: 8870348

Claim:
A liquid ejecting head comprising: a flow path formation substrate on which an individual flow path communicating with a nozzle opening for ejecting liquid is provided; a first member that is provided at one surface side of the flow path formation substrate and has a pressure generation unit which generates pressure change in liquid in the individual flow path; and a second member that is provided at another surface side of the flow path formation substrate, which is opposite to the first member, wherein the liquid ejecting head is a liquid ejecting head formed by a calcined member in which the flow path formation substrate, the first member and the second member are integrated with one another, a dummy flow path is provided on the flow path formation substrate independently of the individual flow path, and an exposure portion that directly exposes a part of wall surfaces of the flow path formation substrate, which form the dummy flow path, so that the part of the wall surfaces is viewable through the exposure portion from outside the first member or the second member and forms an exposed portion, the exposure portion is provided on at least one of the first member and the second member.
