PROBLEM TO BE SOLVED: To reduce a width in a direction of ejection channels 12 of a liquid-jet head 1, and also, to achieve a simple electrode pull-out structure dispensing with a complicated manufacturing step.SOLUTION: The liquid-jet head includes: a piezoelectric substrate 4 including a plurality of grooves 5 which are formed from a front end (FE) to a rear end (RE) of the surface of the substrate and separated from one another by side walls 3, the piezoelectric substrate 4 having lead-out electrodes 8 formed on the top surfaces of the side walls 3; a cover plate 11 which includes a manifold 9 and is bonded to the surface of the piezoelectric substrate 4; and a sealing material 14 for blocking openings of rear channels 10 located closer to the rear end (RE) side among channels constituted of the cover plate 11 and the grooves 5 than the manifold 9. |
