Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ventilation device capable of improving stability in controlling an air volume.SOLUTION: A ventilation device includes: an air supply fan 3SA; and an exhaust fan 3EA for sucking the air and blowing out the same. The air supply fan 3SA and the exhaust fan 3EA include: an impeller 30 rotation-driven; a fan case 31 provided with a fan case air trunk 31c generating airflow of blowing-out of the air sucked from a fan suction portion from a fan blowout port 31b by rotation-driving the impeller 30; and an air volume detection sensor 32 disposed on the fan case 31 and detecting an air volume of the air passing through the fan case air trunk 31c.
