LIQUID EJECTING HEAD

Abstract: there is provided a liquid ejecting head capable of suppressing the breakage of a metallic layer connected to a piezoelectric element resulting from a hydrogen ion while suppressing upsizing. the liquid ejecting head has a first substrate provided with a piezoelectric element on one surface, a second substrate provided the one surface of the first substrate and having a space configured so that the piezoelectric element is positioned internally, and a third substrate bonded to the other surface of the first substrate and including a pressure chamber deforming by driving the piezoelectric element and a liquid ejection opening capable of ejecting liquid supplied to the pressure chamber, and in the space, a low-potential electrode which is at a lower potential than one of an electrode in the piezoelectric element is formed on the one surface of the first substrate.
