Abstract
Provided is an element substrate with suppressed variations in resistance though having a high resistance. In an element substrate equipped with a heat generating resistor that generates thermal energy for ejecting a liquid, the heat generating resistor is a stacked structure having stacked a plurality of resistor layers including a first resistor layer and a second resistor layer containing a metal silicon nitride and the first resistor layer and the second resistor layer are different from each other in at least one of a silicon content in the metal silicon oxide and a metal element contained in the metal silicon nitride.
