摘要： A liquid ejecting head of a side shooter type includes a plate including a plurality of nozzles arranged along a first direction and an actuator with a plurality of pressure chambers arranged along the first direction. Each pressure chamber communicates with a corresponding one of the nozzles. The actuator further includes dummy chambers, each of which is between two otherwise adjacent pressure chambers. Common chambers are provided in the actuator. The pressure and dummy chambers are arranged between the common chambers. The end portions of the pressure chambers are connected to a common chamber. The width of the end portions of each of the pressure chambers is less than the width of a portion of the pressure chamber between the end portions.
