An electric fan includes a motor unit, an air blowing unit disposed on the motor unit and able to be driven by the motor unit to blow air, and a support unit disposed below the motor unit to support the motor unit. The air blowing unit includes a rotary shaft that upwardly extends from the motor unit and that has a peripheral surface surrounding a rotation axis, which extends along a lengthwise direction of the electric fan, and at least one blade. The blade has a base portion connected to the peripheral surface of the rotary shaft and extending along the rotation axis, and an extension portion radially and outwardly extending from the base portion. |
