Provided is an ion generating apparatus, including a housing and an ion generating unit. A waterproof part is provided below an air outlet. The waterproof part includes a discharge port penetrating the waterproof part and in communication with an inside of the housing, and a guide part having a receiving space for receiving a liquid flowing in from the air outlet and guiding the liquid to the discharge port while bypassing an ion exhaust port. By providing the waterproof part below the air outlet to receive the liquid flowing in from the air outlet, the ion generating apparatus may not only prevent the liquid from entering the ion generating unit through the ion exhaust port to affect an ion generation, but also allow a liquid entering the inside of the housing to flow out of the housing along a path that does not come into contact with an electrical component.
