PROBLEM TO BE SOLVED: To provide a mesh type nebulizer which allows a user to perform maintenance easily and which can reduce a burden of cost for a replacement member on the user.SOLUTION: A mesh type nebulizer includes a body 10 having a recess 16 of a shape opened upward. The body 10 includes a vibration part having a vibration surface 43 and a liquid supply part for supplying liquid toward a vibration surface 43. The body also includes a cap member 30 for covering the upper part of the body 10 so as to open/close it, and a replacement member 20 configured separated from the body 10 and the cap member 30, which is removably fitted in the recess 16 of the body 10 beforehand when the nebulizer is used. The replacement member 20 includes a film-like mesh part 21a, a bottom plate part 22, and a side wall part 23. When the cap member 30 is closed for the body 10, a projection part 33 of the cap member 30 presses the bottom plate part 22 of the replacement member 20 against a bottom face 16b of the recess 16, and positions the replacement member 20 with respect to the vertical axis direction of the body 10.SELECTED DRAWING: Figure 1【課題】ユーザにとって、手入れが簡単で、交換部材のための費用負担が少なくて済むメッシュ式ネブライザを提供すること。【解決手段】上方へ向かって開いた形状の凹部１６を有する本体１０を備える。本体１０は、振動面４３を有する振動部と、振動面４３上へ向けて液体を供給する給液部とを含む。本体１０の上部を開閉可能に覆うキャップ部材３０と、本体１０およびキャップ部材３０から分離して構成され、ネブライザが使用される際に予め本体１０の凹部１６に着脱可能に装着される交換部材２０とを備える。交換部材２０は、フィルム状のメッシュ部２１ａと、底板部２２と、側壁部２３とを含む。本体１０に対してキャップ部材３０が閉じられると、キャップ部材３０の突起部３３が交換部材２０の底板部２２を凹部１６の底面１６ｂへ向かって押圧して、本体１０の縦軸方向に関して交換部材２０を位置決めする。【選択図】図１
