摘要:
A liquid ejecting head includes: a nozzle substrate including a first nozzle; a vibration plate; a pressure chamber substrate including a first pressure chamber in which pressure for ejecting liquid through the first nozzle is applied to liquid by the vibration plate and a first absorption chamber in which vibration of liquid propagated from the first pressure chamber is absorbed by the vibration plate; and a sealing substrate including a first-pressure-chamber recess associated with the first pressure chamber and a first-absorption-chamber recess associated with the first absorption chamber, and when a first direction is defined as a direction in which the first pressure chamber and the first absorption chamber are aligned, width of the first-absorption-chamber recess in the first direction is smaller than width of the first absorption chamber in the first direction.
