A mesh nebulizer that atomizes and ejects liquid through a mesh portion includes a vibration portion including a vibration surface facing upward, a liquid supply portion that supplies liquid toward the vibration surface of the vibration portion, a sheet including the mesh portion, and a support frame that supports a peripheral edge of the sheet. The support frame includes a bottom plate that supports a lower surface of the peripheral edge of the sheet, the bottom plate having a flat annular shape, and a larger inner diameter than a diameter of the vibration surface, and a protrusion radially protruding inward from the bottom plate. The sheet including the mesh portion faces the vibration surface at an inclination angle and is in contact with a first portion of a peripheral edge of the vibration surface. The protrusion of the support frame is in contact with a second portion of the peripheral edge of the vibration surface, the second portion opposing the first portion, and maintains the sheet with respect to the vibration surface at the inclination angle.
