A fan structure mainly comprises a fan wheel, a circuit board and a stator. The fan wheel comprising a hub and a plurality of blades is disposed at a fan wheel-disposing area of the circuit board. The fan wheel-disposing area comprises a first disposition area corresponding to the hub and a second disposition area corresponding to the blades. The fan wheel is smaller than the circuit board in size. The stator is disposed at the fan wheel-disposing area, coupled to the fan wheel and electrically connected with a fan-driving circuit of the circuit board.
