Head chip, liquid jet head, and liquid jet recording device

Abstract

A head chip, a liquid jet head, and a liquid jet recording device which effectively transfer elastic energy to ink in a pressure chamber to increase pressure to be generated in the pressure chamber are provided. The head chip according to an aspect of the present disclosure includes an actuator plate provided with a pressure chamber in which a liquid is contained, a jet hole plate which has a jet hole communicated with the pressure chamber, and which is overlapped on the actuator plate in a thickness direction of the actuator plate, and a drive electrode which is configured to generate an electric field in the actuator plate to thereby deform the actuator plate in the thickness direction and a crossing direction crossing the thickness direction to expand or contract a volume of the pressure chamber.

Dependencies are inferred from the claim text.
