The centrifugal fan is a multi blade fan that takes gas in from a rotational axis line direction and blows the gas out in a direction that intersects the rotational axis line, and comprises an impeller and a bell mouth. The impeller rotates about the rotational axis line. The bell mouth has an inlet arranged so that it opposes the impeller, and a recessed part around the inlet that forms a recessed negative pressure space facing the impeller side, and guides the inlet gas to the impeller.
