PROBLEM TO BE SOLVED: To reduce propagation of electromagnetic vibration of an axial fan to an external device. SOLUTION: This axial fan 100 integrally forms an electric motor holding part 7 for holding an electric motor for rotating a blade 10, a venturi 1, and a connecting part 9. The connecting part 9 has an installing part 91 extending in the shaft direction from an end surface of a wind tunnel part 1a of the venturi 1, and a connecting leg 92 connected to the electric motor holding part 7 by crossing a ventilation flue by integrally extending from the installing part 91. The cross-sectional area A1 of the installing part is formed larger than the cross-sectional area A of the connecting leg, and a circumferential directional width of the installing part 91 viewed from the shaft direction is formed larger than a width of the connecting leg 92.
