PROBLEM TO BE SOLVED: To provide a liquid jetting device and a wiping method in the liquid jetting device capable of well wiping a liquid jetting part having projection parts.SOLUTION: The liquid jetting device includes a liquid jetting part 13 which has nozzle arrays 41-46 formed by arranging a plurality of nozzles 20 along the extending direction W and jets a liquid from the nozzles 20, and a wiper 24 which moves relatively to the liquid jetting part 13 in the wiping direction X1 to wipe the liquid jetting part 13. The liquid jetting part 13 comprises the plurality of nozzle arrays 41-46 formed with an interval in the wiping direction X1, projection parts 51-54 positioned between the nozzle arrays 41-46 in the wiping direction X1, and a plane part 56 positioned in both sides of projection parts 51-54 in the extending direction W. The wiper 24 wipes the liquid jetting part 13 with a first relative moving speed so as to collecting the liquid adhered to the liquid jetting part 13 to the plane part 56, and then, wipes the liquid jetting part 13 with a second relative moving speed faster than the first relative moving speed so as to move the liquid adhered to the plane part 56.SELECTED DRAWING: Figure 2 【課題】凸部を有する液体噴射部の払拭を良好に行うことができる液体噴射装置、液体噴射装置における払拭方法を提供する。【解決手段】複数のノズル２０が延設方向Ｗに沿って並ぶことで形成されたノズル列４１〜４６を有し、ノズル２０から液体を噴射する液体噴射部１３と、液体噴射部１３に対して払拭方向Ｘ１に相対移動して液体噴射部１３を払拭するワイパー２４とを備え、液体噴射部１３は、払拭方向Ｘ１に間隔を有して形成された複数のノズル列４１〜４６と、払拭方向Ｘ１においてノズル列４１〜４６の間に位置する凸部５１〜５４と、延設方向Ｗにおいて凸部５１〜５４の両側に位置する平面部５６とを有し、ワイパー２４は、液体噴射部１３に付着した液体を平面部５６に集めるように第１相対移動速度で液体噴射部１３を払拭した後、平面部５６に付着した液体を移動させるように第１相対移動速度よりも速い第２相対移動速度で液体噴射部１３を払拭する。【選択図】図２
