A liquid ejecting head that includes a first piezoelectric element and a second piezoelectric element, a first wire that extends in a first direction and that electrically couples the first piezoelectric element and a wiring substrate to each other, and a second wire that is adjacent to the first wire in a second direction intersecting the first direction and that extends in the first direction, the second wire electrically coupling the second piezoelectric element and the wiring substrate to each other. A first protrusion is formed on a surface of the first wire in a mounting area to where the wiring substrate is joined, and a second protrusion is formed on a surface of the second wire in the mounting area and at a position different from that of the first protrusion in the first direction.
