Abstract: There are provided a head chip, a liquid jet head, a liquid jet recording device, and a method of manufacturing the head chip each capable of preventing the short circuit of electrodes by ink to maintain an excellent ejection performance over a long period of time. The head chip according to an aspect of the present disclosure includes an actuator plate, a cover plate, and an intermediate plate. In the actuator plate, open apertures which communicate an inside and an outside of a non-ejection channel with each other are formed in both end portions of the non-ejection channel in a Y direction. In the actuator plate, open apertures which communicate an inside and an outside of a non-ejection channel with each other are formed in both end portions of the non-ejection channel in the Y direction.
