ABSTRACT:
An organic material is used as the protective film in the ink ejecting printer head with the surface roughness Ra of the protective film is set to be no greater than 3 .mu.m. Accordingly, the segregation of ink components is suppressed to ensure a smooth flow of ink. As a result, the variations in the volume of the ink droplets ejected is reduced and the ejecting stability is improved. Therefore, the ink ejecting printer head having such a protective film that is excellent in protection also improves the stability of the ejected ink droplets and can be manufactured at a low cost.
