<p>Disclosed is a nebulizer kit (100) comprising: a case (110); a flow path forming body (130) that blocks an opening (110c) in the upper section of the case (110); and a cylindrical aerosol discharge port (132) that penetrates a section close to the outer periphery on the upper surface of the flow path forming body (130). A rotation mechanism is provided in the case (110) and/or the flow path forming body (130), for rotating the case (110) in the circumferential direction such that the position of the aerosol discharge port (132) is at a distance from the underside in the vertical direction if the case (110) has overturned and the aerosol discharge port (132) becomes positioned at the underside of the vertical direction in the upper surface of the flow path forming body (130). Even if the nebulizer kit (100) overturns, spillage of fluid stored inside the nebulizer kit (100) is suppressed.</p>
