ABSTRACT:
The present invention relates to a liquid jetting head, a liquid jetting apparatus, and a method of manufacturing the liquid jetting head. The invention can be particularly adopted to an ink jet printer of a thermal system. A treatment for building up a coating type insulating material film and a treatment for substantially removing the insulating material film in the forming regions of heating elements by etching are repeated at least a plurality of times, whereby deterioration of the heating elements can be prevented even in the case where generation of steps is prevented by an SOG film.
