Abstract
A nebulizer kit includes a case body having a compressed air introduction tube, in an upper end portion of which a nozzle hole that expels compressed air is formed, a suction channel formation member that forms a suction channel for sucking a liquid toward the upper end portion and that forms an atomizing area in an exit region of the nozzle hole, and a flow channel formation member having an aerosol discharge port. The suction channel has a first suction channel extending upward along an outer circumferential surface of the compressed air introduction tube, and a second suction channel that extends from the first suction channel toward the nozzle hole at a leading end area of the compressed air introduction tube and has a liquid suction port that expels the liquid.
