PROBLEM TO BE SOLVED: To provide a small centrifugal fan of low noise for restraining vibration. SOLUTION: This small centrifugal fan has an impeller 2 having a blade part for juxtaposing a plurality of blades 21 at a predetermined interval in the circumferential direction, a motor for rotatingly driving the impeller 2, and a substantially cylindrical housing 1 for storing the impeller 2 and the motor. A suction port 121 is formed on the tip side in the shaft direction of the housing 1, and a blowout port 111 is formed in a part of a side surface of the housing 1. The housing 1 has a cylinder part 11 for forming the blowout port 111, and a cap part 12 fixed to the tip side in its shaft direction and forming the suction port 121. The cap part 12 is composed of one metallic plate or a plurality of laminated metallic plates. COPYRIGHT: (C)2006,JPO&NCIPI
