Abstract
A liquid ejection head includes a plate with a plurality of nozzles arranged along a first direction through which liquid is ejected. A substrate is on the plate and includes a hole extending along the first direction by which the liquid is supplied. An actuator is on the substrate along the hole. The actuator has a plurality of pressure chambers, from which the liquid from the hole is ejected by the nozzles, and a plurality of air chambers. Each air chamber is between two of the pressure chambers that are adjacent to each other. A plurality of individual electrodes is formed on the substrate and each is connected to a corresponding one of the pressure chambers. A common electrode is formed on the substrate and an inner peripheral surface of the hole.
