PROBLEM TO BE SOLVED: To appropriately control the amount of anion generation by simple and low-cost structure without employing a special sensor by generating anions in the air blown into the cabin and controlling the anion generation according to air intake status whether inside air or outside air is taken in to the air conditioner duct, vehicle speed, air blowing amount within the air conditioner duct, etc. SOLUTION: An anion generating unit 26 employs, for example, a method in which discharge voltage is applied to a needle electrode so that discharge voltage is controlled to adjust the amount of anions to be generated. An anion generation control unit 25 controls the amount of anion generation based on an air intake mode signal 21, a vehicle speed signal 22, and a wind volume signal 23, which are sent from an air conditioner control unit 20, respectively. In the outside air intake mode, anion generation is increased based on the assumption that exterior exhaust gas, etc., may be taken in. Also when a large amount of air is to be blown, anion generation is increased based on the assumption that powerful air circulation or ventilation is required. Further, in a congested road, due to a high risk of exterior exhaust gas entering the cabin, anion generation is increased, too.
