Original Abstract Submitted
According to one embodiment, a liquid ejection head includes an actuator with a plurality of pressure chambers spaced from each other in a first direction. Each pressure chamber extends lengthwise in a second direction intersecting the first direction. An anti-reflection film is on an inner surface of the pressure chambers. A diaphragm portion is at an end of each pressure chamber. The diaphragm portion provides a flow cross-section that is less than the pressure chamber and is between the pressure chamber and a common chamber to which the pressure chambers are fluidly connected.
