To reduce occurrence of an obstacle such as nozzle clogging by suppressing generation of a gap between a lid part and a support part.SOLUTION: A liquid discharge device includes a flow channel member in which a storage chamber for storing liquid is arranged, a nozzle plate on which a nozzle for discharging the liquid stored in the storage chamber is arranged, a flexible film which structures a part of a wall part of the storage chamber, a support part of the flexible film on which an opening for surrounding a space for exposing the flexible film is arranged at an opposite side to the storage chamber, a lid part which covers the opening by adhering to the support part with an adhesive on a surface opposite to the flexible film of the support part. A groove part is arranged on the surface of the support part at a position at an opposite side to the nozzle with the space interposed therebetween, and the adhesive is also positioned in the groove part.SELECTED DRAWING: Figure 3 【課題】蓋部と支持部との間の隙間の発生を抑制してノズル詰まり等の障害の発生を低減する。【解決手段】液体吐出装置は、液体を貯留する貯留室が設けられている流路部材と、前記貯留室に貯留される液体を吐出するためのノズルが設けられているノズル板と、前記貯留室の壁部の一部を構成する可撓膜と、前記可撓膜のうち前記貯留室とは反対側において前記可撓膜が露出する空間を囲む開口が設けられている支持部と、前記支持部のうち前記可撓膜とは反対側の表面において接着剤により前記支持部と接着されて前記開口を覆う蓋部と、を備え、前記支持部の前記表面には、前記空間を挟んで前記ノズルとは反対側の位置に、溝部が設けられており、前記接着剤は、前記溝部の中にも位置する。【選択図】図３
