Abstract
A liquid ejecting head includes: a pressure chamber; a piezoelectric element that generates energy for applying pressure to an ink in the pressure chamber; a nozzle channel that extends in the X-axis direction and communicates with a nozzle for ejecting the ink; a supply communication channel which enables the pressure chamber and the nozzle channel to communicate with each other; a discharge communication channel which communicates with the nozzle channel; a wiring substrate electrically coupled to a drive circuit that drives the piezoelectric element; and a wiring section that electrically couples the wiring substrate and the piezoelectric element, in which, as viewed in the Z-axis direction orthogonal to the X-axis direction, the wiring section is provided at a position at which the wiring section overlaps the nozzle channel, and the wiring section extends in the ±Q direction, which differs from the X-axis direction.
