A ventilator is provided. The ventilator includes blowers 60 and 70 ; ducts 62 and 72 that are connected to the blowers 60 and 70 to form a blow path having at least one bent part; and a sound-absorbing material 90 that is provided in the bent part of the blow path of the ducts 62 and 72 to absorb noise within the blow path thereof. Therefore, it is possible to remarkably reduce or prevent flow noise that is propagated to the inside of a room as noise of a flow passing through the ducts 62 and 72 is absorbed by the sound-absorbing material 90.
