<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet head is which man-hours can be reduced by efficiently processing a sealing plate. Ž<P>SOLUTION: The method for manufacturing a liquid jet head 1000 includes a step of forming a piezoelectric element 200 above a substrate 100, a step of forming a sealing plate 300, and a step of sealing the piezoelectric element 200 by arranging the sealing plate 300 above the substrate 100. The step of forming the sealing plate 300 includes a step of preparing a glass substrate 310, a laser irradiation step of forming an etching region 312 by irradiating the glass substrate 310 with a laser beam 10, and a step of removing the etching region 312 by a wet etching.
