Abstract: PROBLEM TO BE SOLVED: To easily manufacture a centrifugal fan for a fertilization device for conveying powdery and granular fertilizer fed from a hopper up to a fertilization place by a wind power without reducing the strength of an auxiliary vane. SOLUTION: An impeller 52 stored in a casing is formed by a resin integral molding constituted such that many main vanes 63 and auxiliary vanes 64 having curved radial shapes are protrudedly provided in an overhang manner on one side face of a disclike impeller side plate 61 and a boss 62 is protrudedly provided at the center of one side face of the impeller side plate 61. The main vane 63 is formed consecutively from the boss 62 to an outer peripheral end of the impeller side plate 61, the auxiliary vane 64 positioned between the main vanes 63 is formed from a position where it is apart on an outer side in the radial direction from the boss 62 to an outer peripheral end of the impeller side plate 61, and a height h3 of the auxiliary vane 64 is set to be lower than a height h2 of the main vane 63.
