发明名称 LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS
摘要 A liquid ejecting head includes a flow path formation substrate on which individual flow paths communicating with nozzle openings for ejecting liquid are provided, a first member which is provided at one surface side of the flow path formation substrate and has pressure generation units for generating pressure change in liquid in the individual flow paths, and a second member which is provided at a surface side of the flow path formation substrate, which is opposite to the first member. Dummy flow paths are provided on the flow path formation substrate independently of the individual flow paths. Exposure portions which expose a part of wall surfaces of the flow path formation substrate which form the dummy flow paths, are provided at least one of the first member and the second member.
