LIQUID DISCHARGE HEAD, LIQUID DISCHARGE DEVICE, AND MANUFACTURING METHOD OF LIQUID DISCHARGE HEAD

To reduce variations in a height of a sealing resin applied to a part between a base plate and a cover member in a liquid discharge head in which a plurality of base plates are inclined and aligned.SOLUTION: A liquid discharge head includes a cover member 103 having a plurality of liquid discharge base plates 101 adjacently aligned in a row and an opening part 31, a support member 102, and a sealing part 112. The liquid discharge plate 101 has a first side 14a on one side in an aligning direction and a second side 14b on the other side. A first base plate and a second base plate which are adjacent to each other are arranged in such a manner that the first side 14a of the first base plate faces the second side 14b of the second base plate. The first side 14a and the second side 14b extend to incline relative to a conveying direction of a recording medium. The first side 14a partially overlaps the second side 14b when viewed in the aligning direction. The opening part 31 includes a part which is formed to extend in the aligning direction while bending by following a side constituting a quadrilateral shape of an outer peripheral end surface 12.SELECTED DRAWING: Figure 3 【課題】複数の基板が傾いて配列される液体吐出ヘッドにおいて、基板とカバー部材との間に塗布される封止樹脂の高さのばらつきを低減する。【解決手段】隣接して一列に並ぶ複数の液体吐出基板１０１と開口部３１を有するカバー部材１０３と、支持部材１０２と、封止部１１２と、を備え、液体吐出基板１０１は、配列方向の一方の側の第１の辺１４ａと、他方の側の第２の辺１４ｂと、を有し、互いに隣接する第１の基板と第２の基板は、第１の基板の第１の辺１４ａが第２の基板の第２の辺１４ｂに対向するように配置され、第１の辺１４ａと第２の辺１４ｂは、記録媒体の搬送方向に対して傾斜して延び、第１の辺１４ａは、第２の辺１４ｂに対して、配列方向で見たときに部分的に重なる液体吐出ヘッドであって、開口部３１は、外周端面１２の四角形状を構成する辺に倣って屈曲しながら配列方向に延びるように形成される部分を含むことを特徴とする。【選択図】図３
