PROBLEM TO BE SOLVED: To provide a centrifugal fan capable of discharging air both in the radial direction and in the axial direction of an impeller. SOLUTION: The centrifugal fan (22) includes: a fan casing (26) and the impeller (27). The fan casing (26) is provided with suction ports (33, 34) sucking air, a first discharge port (35) and a second discharge port (36) discharging air. The first discharge port (35) is opened in a different direction from the suction ports (33, 34). The second discharge port (36) is opened in the same direction as the suction ports (33, 34) at a position separate from the impeller (27). COPYRIGHT: (C)2011,JPO&INPIT
