An ejection head cartridge and an inhalation apparatus may limit turbulence in an air stream and reduce the likelihood of collisions of ejected drug in an air flow channel so that the drug can be conveyed in a uniform air stream. An ejection head cartridge that is attachable to an inhalation apparatus for ejecting drug for inhalation by a user and has a plurality of ejection ports includes, among end portions continuous to a surface provided with the ejection ports, an end portion parallel to an ejection port array having a shape that guides a part of the air stream generated in the direction orthogonal to the ejection-port providing surface along the surface. |
