A liquid ejecting head includes a pressure chamber that applies a pressure of a liquid for ejecting a liquid from a nozzle when a first piezoelectric element is driven, and a detection chamber in which a second piezoelectric element detects a residual vibration of the pressure of the liquid applied in the pressure chamber. The first piezoelectric element includes a first piezoelectric body, a first upper electrode, a first lower electrode, and a first vibration plate provided below the first lower electrode, the second piezoelectric element includes a second piezoelectric body, a second upper electrode, a second lower electrode, and a second vibration plate provided below the second lower electrode, and a neutral axis of the second piezoelectric element is positioned above a neutral axis of the first piezoelectric element.
