    Abstract: A discharge element substrate comprises a plurality of discharge elements each including a first electrical contact and a second electrical contact, a plurality of driving circuits arranged in a first direction and each connected to the plurality of discharge elements, and a plurality of driving wiring lines extending in a second direction that intersects with the first direction and configured to connect the plurality of driving circuits and the first electrical contact of the plurality of discharge elements. A length, in the second direction, of a first driving wiring line connecting the first driving circuit and the first electrical contact of the first discharge element is shorter than a length, in the second direction, of a second driving wiring line connecting the second driving circuit and the first electrical contact of the second discharge element.
