Abstract
A head chip, a liquid jet head, and a liquid jet recording device each capable of increasing pressure generated while achieving power saving are provided. The head chip according to an aspect of the present disclosure includes a flow channel member, an actuator plate, and drive electrodes. The drive electrodes include a first electrode disposed on a first surface of the actuator plate so as to overlap one of a pressure chamber and a partition wall when viewed from a first direction, a second electrode which is disposed on the first surface of the actuator plate so as to be adjacent to the first electrode, and which generates a potential difference from the first electrode, and a first opposed electrode which is individually disposed on a second surface of the actuator plate at a position opposed to the first electrode, and which generates a potential difference from the first electrode.
