PROBLEM TO BE SOLVED: To provide a liquid jet head which inhibits distortion of a base member while correcting warpage of a lamination member such as a passage member, and to provide a manufacturing method of the liquid jet head.SOLUTION: A liquid jet head includes: a liquid jet unit (4) having a nozzle surface on which nozzles (24) open; a base member (51) to which the liquid jet unit (4) is fixed; and a cover member (52) attached to the base member (51) and on which a lamination member (13) is laminated. The cover member (52) has: a fixture part (65) to which the lamination member (13) is fixed; and fragile parts (73) having rigidity lower than that of the fixture part (65) and is fixed to the base member (51) by the fragile parts (73) being fixed to the base member (51).SELECTED DRAWING: Figure 7 【課題】流路部材等の積層部材の反りを矯正しつつ、ベース部材の歪みを抑制できる液体噴射ヘッド、及び、液体噴射ヘッドの製造方法を提供する。【解決手段】ノズル（２４）が開口されたノズル面を有する液体噴射ユニット（４）と、液体噴射ユニット（４）が固定されたベース部材（５１）と、ベース部材（５１）に取り付けられると共に積層部材（１３）が積層されたカバー部材（５２）と、を備え、カバー部材（５２）は、積層部材（１３）が固定される固定部（６５）、及び、固定部（６５）よりも剛性が低い脆弱部（７３）を有し、脆弱部（７３）のベース部材（５１）への固定により当該ベース部材（５１）に取り付けられたことを特徴とする液体噴射ヘッド。【選択図】図７
