PROBLEM TO BE SOLVED: To increase a flow rate of gas led to flow out, and also to reduce dust inside of an electronic device. SOLUTION: This fan device includes: a blade member 2 rotatably provided; a casing 5 rotatably attached with the blade member 2 and having a vent hole 3 of outside air flowed into from one side and flowed out from the other side by the blade member 2, and a through-hole 4 formed in the side surface of the casing for connecting the outside and the vent hole 3; and a first mesh 6 covering the through-hole 4 and collecting gaseous dust flowing in the through-hole 4. Since the outside air can flow into from one side of the vent hole 3 and the through-hole 4 and the flow rate of the outside air flowing out from the other side can be increased, the air volume of the outside air flowing out of the other side of the vent hole 3 can be increased more than ever before. Also, since the first mesh 6 can collect dust in the outside air flow from the through-hole 4 into the vent hole 3, dust in the inside of the electronic device 30 can be reduced.
