Abstract
When a lower surface of a liquid ejecting head is formed by a nozzle plate and a cover member, a surface of the nozzle plate and a surface of the cover member are water-repellent surfaces and side surfaces of the nozzle plate and the cover member are relatively hydrophilic surfaces compared to the surfaces and a gap between the nozzle plate and the cover member is filled with a filling material. If at least the side surface of the nozzle plate is covered by the filling material, the nozzle plate can be protected from static electricity. Further, if the side surface of the cover member is filled with the filling material, wiping by a wiper is improved.
