The present invention relates to an anion generation device for a vehicle, capable of discharging inner air of a vehicle by being connected to a cigar jack of the vehicle to measure an air pollution level and humidity of the inner air of the vehicle and sucking, filtering, and dehumidifying the inner air of the vehicle in accordance with the measured air pollution level and the humidity and of discharging an anion with the inner air, thereby purifying the inner air of the vehicle. Specifically, the anion generation device for a vehicle can create pleasant inner environment of the vehicle by dehumidification even in a condition of high humidity. According to the present invention, the anion generation device for a vehicle includes: a housing having a suction unit formed on the lower surface and a discharge unit formed on the upper surface a connector connected to one side of the housing and connected to the cigar jack of the vehicle a suction fan installed in the housing and discharging an air volume to the discharge unit by sucking the inner air of the vehicle through the suction unit an ionizer installed in the housing and providing the anion to the discharge unit by generating the anion an air purification filter connected to the suction unit a dehumidification bag installed in rear of the suction unit and filled with a dehumidifying agent a face heating element installed close to the dehumidification bag and heating and drying the dehumidifying agent of the dehumidification bag an air pollution measuring sensor installed in the housing a humidity sensor installed in the housing and a control unit installed in the housing and electrically connected to the connector, wherein the control unit controls an operation of the face heating element, the suction fan, and the ionizer in accordance with a measuring signal of the humidity sensor and the air pollution measuring sensor.COPYRIGHT KIPO 2017본 발명은 차량의 시거잭에 접속되어 차량 실내공기의 공기오염도와 습도를 측정하고 측정된 공기오염도와 습도에 따라 차량 내부공기를 흡입하
