PROBLEM TO BE SOLVED: To provide a liquid discharge head in which lowering of an image quality at a tie part between head modules of the liquid discharge head, which has such a structure that plural head modules are tied in one direction, can be suppressed, a liquid discharge head manufacturing method, and a liquid discharge head manufacturing system.SOLUTION: A liquid discharge head (21) having such a structure that three or more head modules (200) equipped with plural discharge elements (281) are located along one direction, in which a first head module (200B), a second head module (200C), and a third head module (200D) are so configured that inclinations of discharge volume distribution in one direction, which are determined in such a manner that discharge volumes at one ends in one direction are subtracted from discharge volumes at the other end are located in ascending order, or inclines of discharge volume distribution in one direction are located in descending order.SELECTED DRAWING: Figure 23 【課題】複数のヘッドモジュールを一方向に繋ぎ合わせた構造を有する液体吐出ヘッドのヘッドモジュール間の繋ぎ部における画像品質の低下を抑制しうる液体吐出ヘッド、液体吐出ヘッド製造方法、及び液体吐出ヘッド製造システムを提供する。【解決手段】複数の吐出素子（２８１）を備えたヘッドモジュール（２００）を一方向に沿って三つ以上配置させた構造を有する液体吐出ヘッド（２１）であって、第一ヘッドモジュール（２００Ｂ）、第二ヘッドモジュール（２００Ｃ）、及び第三ヘッドモジュール（２００Ｄ）は、一方向における一方の端部の吐出体積を一方向における他方の端部の吐出体積から減算して求められる一方向における吐出体積分布の傾きが昇順に配置されるか、又は一方向における吐出体積分布の傾きが降順に配置される。【選択図】図２３
