A centrifugal fan includes a housing, a spiral impeller, a suction interrupting member. The housing includes a suction port and a discharge port. The housing further includes an outwardly curved cutoff portion at a side of the discharge port. The spiral impeller is coupled with a motor to suck air through the suction port of the housing in a rotation-axis direction and discharge the sucked air through the discharge port in a direction perpendicular to a rotation-axis. The suction interrupting member prevents air from being sucked into a neighborhood of the cutoff portion through the suction port.
