This aims to provide an aerosol aspirator comprising an aerosol producingpassage (6) extending from an outside-airintroduction port (2) to a mouthpiece (4), a liquid supply unit (18) forsupplying a solution of a predetermined quantity to a supplyposition (A) of the aerosol producing passage (6), a ceramic heater (12) forheating and evaporating a solution, which has beentransferred from the supply position (A) toward the mouthpiece (4) togetherwith the suction air to flow in the aerosol producingpassage (6) at the aspiration time of a user, thereby to produce an aerosol inthe aerosol producing passage (6), and a protectordisposed either near the supply position (A) or between the supply position(A) and the liquid supply unit (18). This protectorincludes at least one of a radiation cover (20), a cooling unit (21) or anopen/close valve (22).
