In this air blowing device, the airflow path includes a helical flow path that is a helical airflow path extending as separating from the air inlet. Further, the helical flow path includes an opening formed in an outer circumferential surface of the helical flow path. Further, the opening is connected to the air outlet through a discharge path configured to guide the air passing through the opening to the air outlet.
