PROBLEM TO BE SOLVED: To provide a serial axial flow fan, in which passage resistance between a first axial flow fan and a second axial flow fan is restricted, while a group of lead wires are collected in a passage to be extended outward. SOLUTION: In the serial axial flow fan 1, first support ribs 24 of the first axial flow fan 2 and second support ribs 34 of the second axial flow fan 3 overlap each other in the direction of an axis J1. On one of the first support ribs 24 and the corresponding one of the second support ribs 34, a first lead wire support part 41 and a second lead wire support part 42 are provided to project in the circumferential direction around the axis J1. On the lead wire support parts 41 and 42, recessed parts which face each other are provided, so that a space 81 is formed of the recessed parts. Groups of lead wires 91 and 92 of the first axial flow fan 2 and the second axial flow fan 3 are collected in the passage of air to pass through the space 81. Passage resistance between the first axial flow fan 2 and the second axial flow fan is thus restricted, while the groups of lead wires 91 and 92 can be collected to be brought outward of housings 23 and 33.
