This article relates to an axial fan with double impellers rotating in mutually opposite directions to be used for cooling an electronic component. The fan takes in air through an opening provided at one of the ends of the article in an axial direction, and discharges the air out of an opening provided at the other end of the article in the axial direction. Inside the air intake opening, an impeller having five blades is installed. Inside the air discharge opening, an impeller having four blades is installed. The impeller having five blades and the one having four blades rotate in an opposite direction to each other.
