This mesh-type nebulizer (1) which causes a medical liquid (23) to pass through a mesh section (24a) to atomize the medical liquid (23) and discharges the atomized medical liquid (23) is provided with: a body (10) provided with a vibration section (40) having a vibration surface (43); and a medical liquid package (20) removably mounted to the body (10). The medical liquid package (20) is provided with: a cover member (21) having the mesh section (24a) formed therein; and a medical liquid storage member (24) having a recess (17) which is open toward the mesh section (24a) and which is covered with the cover member (21), the recess (17) having a medical liquid stored therein. A portion of the bottom surface (24c) of the recess (17) in the medical liquid storage member (24), the portion being to face at least the vibration surface (43), is formed from a stretchable material. When the medical liquid package (20) is mounted to the body (10), the stretchable material of the bottom surface (24c) stretches to permit the vibration surface (43) to move toward the mesh section (24a) of the cover member (21).L'invention concerne un nébuliseur de type treillis (1) qui provoque le passage d'un liquide médical (23) à travers une section de treillis (24a) pour atomiser le liquide médical (23) et évacue le liquide médical atomisé (23), pourvu de : un corps (10) pourvu d'une section de vibration (40) présentant une surface de vibration (43) ; et un emballage (20) de liquide médical monté de façon amovible sur le corps (10). L'emballage (20) de liquide médical comprend : un élément de couvercle (21) présentant la section de treillis (24a) formée en son sein ; et un élément (24) de stockage de liquide médical présentant un creux (17) qui est ouvert vers la section de treillis (24a) et qui est recouvert par l'élément de couvercle (21), le creux (17) présentant un liquide médical stocké en son sein. Une partie de la surface de fond (24c) du creux (17) dans l'élément de stockage (24) de l
