PROBLEM TO BE SOLVED: To provide a centrifugal fan of low power consumption and low noise by improving the efficiency of the fan. SOLUTION: In this centrifugal fan, a plurality of blades are mounted between a front shroud and a rear shroud in a state of alternately arranged two kinds of first and second blades of different shape, to inhibit the turbulence near an inner wall of the front shroud, and unifying the distribution of a flow speed among the blades.
