    摘要: A liquid drop ejecting head for ejecting liquid drops from nozzles communicating with liquid chambers includes a piezoelectric actuator including a diaphragm whose ends are fixed in a short-side direction of the diaphragm and an active element mounted on the diaphragm. The active element is contractible and extendable by a supply of a voltage to displace the diaphragm in an out-of-plane direction. The diaphragm is displaced with curvature so as to have a plurality of inflection points in the short-side direction. The active element is disposed in at least one area of an area from each of the ends of the diaphragm to a proximal inflection point of the inflection points and an area from one inflection point to another neighboring inflection point of the inflection points in a cross-section in the short-side direction of the diaphragm.

    摘要: A liquid drop ejecting head includes a a nozzle plate to form nozzles, a liquid chamber substrate including one surface bonded to the nozzle plate and forming liquid chambers provided for the nozzles and communicating with the nozzles, a diaphragm bonded to the other surface of the liquid chamber substrate to form a part of each liquid chamber, and a pressure generating unit giving pressure oscillation to the diaphragm in accordance with a liquid drop eject signal to exert pressure on a liquid in each liquid chamber through the diaphragm. In the liquid drop ejecting head, a protection film is formed on an inner side wall of each liquid chamber by a chemical reaction of fluorocarbon and silicon fluoride oxide of a by-product formed on the inner side wall of the liquid chamber with the formation of the liquid chambers in the liquid chamber substrate.
