PROBLEM TO BE SOLVED: To increase a mechanical strength of an element which forms a space in which liquid is charged.SOLUTION: A liquid jet head 100 includes a pressure chamber substrate 34 in which a pressure chamber space 342 is formed, a first surface F1 on which the pressure chamber substrate 34 is located and a second surface F2 opposite to the first surface F1, and comprises: a space R1; a channel substrate 32 which is provided with a supply hole 322 which communicates the space R1 and the pressure space 342 with each other, and a continuous hole 324 which communicates with the pressure chamber space 342; a nozzle plate 52 which is located on the second surface F2 and is provided with a nozzle N which communicates with the continuous hole 324; a housing body part 40 which is provided with a space R2 which is located on the first surface F1 and communicates with the space R1 of the channel substrate 32, and an opening 422 which communicates with the space R2; a flexible compliance part 54 which is located on the second surface F2 and which seals the continuous hole 324 and the space R1; and a beam-like part 48 bridging over internal wall surfaces of the space R2 in the housing body part 40.SELECTED DRAWING: Figure 3 |
