Liquid ejecting head and liquid ejecting apparatus including the same

A liquid ejecting head that ejects a liquid from a nozzle opening, comprising:

• a first channel-forming substrate including a pressure-generating chamber a part of which is constituted by a diaphragm;
• a second channel-forming substrate disposed on a surface opposite the diaphragm of the first channel-forming substrate;
• an actuator that includes the diaphragm and that applies a pressure to the pressure-generating chamber to eject the liquid from the nozzle opening;
• a first protective film having liquid resistance and disposed on an inner surface of the pressure-generating chamber;
• and
• a second protective film having liquid resistance and disposed on at least a surface of the second channel-forming substrate, the surface facing the first channel-forming substrate,
• wherein the first channel-forming substrate is bonded to the second channel-forming substrate with an adhesive provided between the first protective film and the second protective film, and
• a contact angle θ1 of a surface of the first protective film to the adhesive before curing is larger than a contact angle θ2 of a surface of the second protective film to the adhesive before curing.
