An element substrate includes a discharge port that discharges a liquid, an energy-generating element that generates energy that discharges the liquid from the discharge port, an acting chamber that makes the energy of the energy-generating element act on the liquid, and a heating element including at least two heat generating surfaces that are exposed to the liquid inside the acting chamber, the heating element disposed inside the acting chamber. The element substrate further includes a substrate in which a supply port that supplies liquid to the acting chambers is formed. The heating element may be disposed such that the heat generating surfaces are spaced apart from the substrate.
