A head chip, a liquid jet head, and a liquid jet recording device each capable of inhibiting mechanical crosstalk, and exerting a desired jet performance are provided. The head chip according to an aspect of the present disclosure includes a flow channel member having a plurality of pressure chambers containing liquid, an actuator plate which is stacked on the flow channel member in a state of being opposed in a first direction to the pressure chambers, and a drive electrode which is formed on a surface of the actuator plate, the surface facing to the first direction, and which is configured to deform the actuator plate in the first direction to change a volume of at least one of the pressure chambers. A dividing groove which is configured to zone the actuator plate between the pressure chambers adjacent to each other is formed in a portion of the actuator plate, the portion being located between the pressure chambers adjacent to each other when viewed from the first direction.
