Abstract: A non-exhaust fine dust collecting apparatus using friction electricity is disclosed. An exemplary embodiment of the present invention provides a non-exhaust fine dust collecting apparatus using friction electricity, including: an air pipe mounted in a vehicle and provided with an inlet through which fine dust generated in a vehicle and charged with a first polarity flows together with air; and a dust collector mounted at a side of an outlet of the air pipe and charged with a second polarity that is opposite to the first polarity to collect the fine dust charged with the first polarity.
