PROBLEM TO BE SOLVED: To inexpensively manufacture a high-density long ink jet head in a simple method. SOLUTION: A jetting force-generating mechanism 13 for jetting liquid drops from nozzle holes 11 is formed in a simple batch process. A substrate with the jetting force-generating mechanisms formed thereto is joined to a base material 12 for forming channels to communicate with the nozzle holes, whereby the high-density long ink jet head is formed. The substrate with the jetting force-generating mechanisms 13 can be joined so that a plurality of the mechanisms are allotted to the channel communicating with the nozzle hole.
