ABSTRACT:
A liquid dispenser includes a substrate and a plurality of liquid-dispensing portions, arranged on the substrate, including at least one liquid chamber for storing liquid, one nozzle, and one heating element, wherein the heating elements are energized to heat liquid stored in the corresponding liquid chambers to eject a droplet of the liquid from the corresponding nozzles; the heating elements and the liquid chambers have a protective layer and an insulating layer therebetween; each heating element, the insulating layer, the protective layer, and each liquid chamber are arranged in that order; the insulating layer isolates the protective layer from the heating elements; and the protective layer comprises an inorganic material, protects the heating elements, has a strip shape so as to cover some of the plurality of heating elements adjacent to each other, and has slits each disposed between the heating elements.
