The present invention provides a liquid-ejecting head, a method of ejecting liquid, and a liquid-ejecting printing apparatus, which permit an image-printing with the high quality by stabilizing volumes, flying velocities, and deposition points of ejected liquid droplets and preventing the generation of splash or mist of the liquid droplets. Thus, a heater having a heating portion on the side of the liquid chamber which is broader than a heating portion of the opposite side of the liquid chamber relative to a projected point where a centroid of any cross section of the orifice in parallel with the substrate is projected on the substrate. A shape of a cross section of the orifice in parallel with the substrate which is projected on the substrate from the side of the orifice plate has a combination of two ellipse portions figures in which a centroid and a plan of the heater are coincident with each other.
