PROBLEM TO BE SOLVED: To provide an electric blower easily responding to a plurality of different characteristics, and improving productivity. SOLUTION: A straightening plate 4 is formed by axially connecting an upstream air passage part 63 and a downstream air passage part 64. The upstream air passage part 63 has a plurality of upstream blades 68 straightening air blown from a centrifugal fan to an outer peripheral side. The downstream air passage part 64 has downstream blades 75 straightening air, which has been straightened by the upstream blades 68, from an outer peripheral side to a motor side of the straightening plate 4. Only by changing a kind of the upstream air passage part 63 to be combined with the downstream air passage part 64, the electric blower can easily respond to the plurality of different characteristics, and the productivity is improved.
