An aerosol inhalator comprising: a suction path (50, 22) connecting an atmosphere-exposed opening and a mouthpiece to each other and permitting air to flow from the atmosphere-exposed opening toward the mouthpiece; a solution supply device (20, 40) configured to supply a solution from which an aerosol is to be generated, said solution supply device including a solution supply source storing the solution, and a capillary tube connected to the solution supply source and having a discharge end located in said suction path and opening in a direction toward the mouthpiece, the capillary tube guiding the solution from the solution supply source to the discharge end and, when the flow of air is produced within said suction path, allowing the solution to be discharged from the discharge end; and a heater device (26, 56) configured to receive the solution discharged from the discharge end of the capillary tube and atomize the received solution by heating, said heater device including a power supply, and an electric heater arranged immediately downstream of the discharge end and facing the discharge end while permitting the flow of air, the heater being configured to generate heat when applied with a voltage from the power supply, wherein the heater extends in a direction perpendicular to an axis of said suction path and traverses said suction path; wherein the discharge end of the capillary tube is arranged in a position such that the discharge end is hidden by the heater when an interior of said suction path is viewed from the mouthpiece side, wherein a distance is secured between the discharge end of the capillary tube and the heater, characterized in that the distance is adapted so that a liquid droplet of the solution is formed at the discharge end by surface tension of the solution and the formed liquid droplet is directly received by a surface of the electric heater. a suction path (50, 22) connecting an atmosphere-exposed opening and a mouthpiece to each other and permitting air to flow from the atmosphere-exposed opening toward the mouthpiece; a solution supply device (20, 40) configured to supply a solution from which an aerosol is to be generated, said solution supply device including a solution supply source storing the solution, and a capillary tube connected to the solution supply source and having a discharge end located in said suction path and opening in a direction toward the mouthpiece, the capillary tube guiding the solution from the solution supply source to the discharge end and, when the flow of air is produced within said suction path, allowing the solution to be discharged from the discharge end; and a solution supply source storing the solution, and a capillary tube connected to the solution supply source and having a discharge end located in said suction path and opening in a direction toward the mouthpiece, the capillary tube guiding the solution from the solution supply source to the discharge end and, when the flow of air is produced within said suction path, allowing the solution to be discharged from the discharge end; and a heater device (26, 56) configured to receive the solution discharged from the discharge end of the capillary tube and atomize the received solution by heating, said heater device including a power supply, and an electric heater arranged immediately downstream of the discharge end and facing the discharge end while permitting the flow of air, the heater being configured to generate heat when applied with a voltage from the power supply, wherein the heater extends in a direction perpendicular to an axis of said suction path and traverses said suction path; wherein the discharge end of the capillary tube is arranged in a position such that the discharge end is hidden by the heater when an interior of said suction path is viewed from the mouthpiece side, a power supply, and an electric heater arranged immediately downstream of the discharge end and facing the discharge end while permitting the flow of air, the heater being configured to generate heat when applied with a voltage from the power supply, wherein the heater extends in a direction perpendicular to an axis of said suction path and traverses said suction path; wherein the discharge end of the capillary tube is arranged in a position such that the discharge end is hidden by the heater when an interior of said suction path is viewed from the mouthpiece side, wherein a distance is secured between the discharge end of the capillary tube and the heater, characterized in that the distance is adapted so that a liquid droplet of the solution is formed at the discharge end by surface tension of the solution and the formed liquid droplet is directly received by a surface of the electric heater.
