LIQUID JET HEAD, LIQUID JET DEVICE AND MANUFACTURING METHOD FOR LIQUID JET HEAD

摘要

PROBLEM TO BE SOLVED: To provide a liquid jet head capable of reducing variations of deformation amount of both bulkheads of a discharge channel and improving recording quality.SOLUTION: A liquid jet head 1 includes: discharge channels C and dummy channels D configuring a channel array CR by being alternately arrayed with bulkheads 3 interposed therebetween; and drive electrodes 6 which are located on side faces of the bulkheads 3 in a depth direction from upper ends of the bulkheads 3. An average depth of the two drive electrodes 6 located on the facing side faces of the discharge channel C is different from an average depth of the two drive electrodes 6 located on facing side faces of the dummy channel D adjacent to the discharge channel C.SELECTED DRAWING: Figure 1
