A liquid ejecting head includes a nozzle, a pressure chamber that applies a pressure for ejecting a liquid from the nozzle by driving a first piezoelectric element, a detection chamber in which a second piezoelectric element detects a residual vibration of the pressure applied in the pressure chamber, an absorption chamber in which a third piezoelectric element absorbs a vibration of the pressure applied in the pressure chamber, and a wiring substrate that electrically couples to an outside of the liquid ejecting head. The first piezoelectric element of the liquid ejecting head is electrically coupled to the wiring substrate, the second piezoelectric element is electrically coupled to the wiring substrate, and the third piezoelectric element, the first piezoelectric element, the wiring substrate, and the second piezoelectric element are disposed side by side in this order, when viewed from an up and down direction.
