Abstract
According to an embodiment, a liquid ejecting head chip includes an actuator plate, a cover plate, a common electrode, and a connection wiring. In the actuator plate, a plurality of discharge channels and a plurality of non-discharge channels which extend in a Z-direction are alternately arranged at a distance in an X-direction. The cover plate is stacked on an AP-side-Y-direction inner side surface, so as to close the plurality of discharge channels and the plurality of non-discharge channels. The common electrode is formed on an inner surface of each of the discharge channels. The connection wiring is divided so as to be formed in at least 3 or more places in the X-direction on the cover plate, and the common electrode connects the connection wiring to the flexible substrate.
