The present invention relates to an apparatus for inhalation of medicine, in which particles in a medicinal aqueous solution, in a liquid aerosol form, are converted to dry medicinal particles by removing moisture therefrom by means of an evaporation unit so as to be inhaled,thereby allowing medicinal particles to penetrate deeply along the respiratory track to the lungs, and thus can be used in the treatment of lung diseases or a variety of other treatments using same, and in which an evaporation unit is structured so that an air compressor used in an aerosol unit is used to supply dry air thereto, thereby obviating an additional and separate device therefor, and thus the apparatus for inhalation is simplified, manufacturing thereof is facilitated and the manufacturing cost thereof is reduced.
