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

Abstract

A head chip, a liquid jet head, and a liquid jet recording device each capable of effectively transferring 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 a flow channel member in which a plurality of pressure chambers penetrating in a first direction is arranged in a second direction crossing the first direction, a first member which includes an actuator plate deformable in the first direction, and which is bonded on the flow channel member in a state of closing the pressure chambers from a first side in the first direction, and a second member which includes a jet hole plate provided with jet holes communicated with the pressure chambers, and which is bonded on the flow channel member in a state of closing the pressure chambers from a second side as an opposite side to the first side in the first direction. The flow channel member includes a partition wall configured to partition the pressure chambers adjacent to each other. The bonding area between the partition wall and the second member is larger than the bonding area between the partition wall and the first member.

Dependencies are inferred from the claim text.
