A heating and blowing apparatus includes a main body housing having an inlet port and a discharge port; a rotatingly driven fan and a heating unit arranged on an air flow path, the air flow path extending from the inlet port to the discharge port; and an ion generator including a discharge electrode and an opposing electrode arranged in a bypass flow path, the bypass flow path branching off from the air flow path and leading to an ion emission port. Further, it includes a cover, arranged at the ion emission port, having an opening through which ions pass and one or more protrusions provided on a rear surface of the cover, the protrusion making contact with the opposing electrode placed closer to the cover than the discharge electrode is, wherein the cover is grounded through the opposing electrode.
