Abstract

A liquid ejecting head includes: a nozzle; a pressure chamber; a supply flow channel which is located on one side in a first direction relative to the pressure chamber and through which a liquid is supplied to the pressure chamber; a discharge flow channel which is located on another side in the first direction relative to the pressure chamber and through which the liquid is discharged from the pressure chamber; a supply-side compliance substrate which absorbs a vibration of the liquid in the supply flow channel; and a discharge-side compliance substrate which absorbs a vibration of the liquid in the discharge flow channel. A length of the discharge-side compliance substrate in the first direction is shorter than a length of the supply-side compliance substrate in the first direction.
