PROBLEM TO BE SOLVED: To provide an axial fan generating high wind pressure. SOLUTION: This axial fan for electronic equipment is constituted so that a ring-shaped centrifugal blower type impeller 3 is rotatably arranged on a common shaft in a housing 2 having a cylindrical inner peripheral surface 4a by an outer rotor type electric motor 10, air taken in from a suction hole 5 arranged in a suction side end surface of the housing 2 is pressurized by the impeller 3 in an axial flow forming chamber 19 of a hollow cylindrical shape formed of an inner peripheral surface 4a of the housing 2 and an outer peripheral surface 15 of an impeller 3, and is then made to flow to the axial directional air delivery side by the axial flow forming chamber 19, and the pressurized air is delivered outside the housing 2 via an air delivery hole 8 arranged in an air delivery side end surface of the housing 2, and efficiently cools the electronic equipment mounted with a highly integrated electronic element.
