Original Abstract Submitted
A liquid ejection device has an element substrate having an ejection port; and a voltage application unit applying a voltage to the element substrate, wherein the element substrate has a first layer having the ejection port and a first channel communicating with the ejection port and a second layer fixed to a back face of the first layer and having a second channel communicating with the first channel, a heat element for ejecting the liquid, a first electrode covering a surface of the heat element on a side of the first layer and exposed to the first channel, and a second electrode exposed to the first channel at a position different from the first electrode and not overlapping the heat element on a plan view, and the voltage application unit is configured to apply the voltage so that the first electrode is at a negative potential.
