The air-powder mixture within the air-powder mixture reservoir is admixed with a diluent air introduced thereinto through the diluent air passage. The diluted air-powder mixture is discharged from an air-powder mixture outlet into a user's oral or nasal cavity. A powder composition for inhalators includes at least two kinds of fine particles different in particle diameter.
