Abstract
A head chip, a liquid jet head, and a liquid jet recording devices each capable of increasing the generated pressure while achieving an increase in manufacturing efficiency and yield ratio are provided. The head chip includes a flow channel member provided with a pressure chamber containing a liquid, an actuator plate on the flow channel member in a state of being opposed in a first direction to the pressure chamber, and a drive electrode configured to deform the actuator plate in the first direction to change a volume of the pressure chamber. A recessed part is formed in a portion of the actuator plate, the portion overlapping the pressure chamber when viewed from the first direction. The drive electrode includes a first electrode formed on an inner surface of the recessed part, and a first opposed electrode which is formed on an upper surface of the actuator plate.
