To provide a liquid spray device capable of stably spraying liquid.SOLUTION: The liquid spray device comprises a tank 201 for storing liquid 10, a spray device 250 having an ejection part 251 ejecting the liquid 10 formed in a mist shape, a first flow passage forming part 210 forming a first flow passage F1 of the liquid 10 between the tank 201 and the ejection part 251, a pump 230 provided in the middle of the first flow passage F1 and sending out the liquid from the tank 201 toward the ejection part 251 and a second flow passage forming part 220 forming a second flow passage F2 which branches from a branch position 217 between the pump 230 and the ejection part 251 of the first flow passage F1 and recirculates to the tank 201. The first flow passage forming part 210 comprises a small cross-sectional area part 218 forming a flow passage of the smaller cross-sectional area than the cross-sectional area of the second flow passage F2 in a position between the branch position 217 of the first flow passage F1 and the ejection part 251.SELECTED DRAWING: Figure 2A 【課題】安定的に液体を噴霧することができる液体噴霧装置を提供する。【解決手段】液体１０を貯留するタンク２０１と、霧状にされた液体１０を吐出する吐出部２５１を有する噴霧装置２５０と、タンク２０１と吐出部２５１との間において液体１０の第一流路Ｆ１を形成する第一流路形成部２１０と、第一流路Ｆ１の途中に設けられ、タンク２０１からの液体を吐出部２５１に向けて送り出すポンプ２３０と、第一流路Ｆ１の、ポンプ２３０及び吐出部２５１の間の分岐位置２１７から分岐してタンク２０１に還流する第二流路Ｆ２を形成する第二流路形成部２２０とを備える。第一流路形成部２１０は、第一流路Ｆ１の分岐位置２１７及び吐出部２５１の間の位置に、第二流路Ｆ２の断面積よりも小さい断面積の流路を形成する小断面積部２１８を有する。【選択図】図２Ａ
