Abstract
An element substrate for a liquid ejecting head includes a substrate, an element forming layer on the substrate, and a discharge port forming member formed of an insulating member on the element forming layer. The element forming layer includes an energy generating element configured to provide energy to a liquid for ejection. The discharge port forming member includes a discharge port forming surface having discharge ports through which the liquid is ejected and an exterior side surface positioned between the discharge port forming surface and the element forming layer. The exterior side surface has a first edge facing the element forming layer. The element substrate further includes a conductive layer disposed between the first edge and the element forming layer and grounded.
