PROBLEM TO BE SOLVED: To provide an ion generation device having a structure allowing even an AC power source of a commercial frequency to be downsized by being integrated with a discharge electrode. SOLUTION: This ion generation device 1 generates corona discharge from the discharge electrode 2 by applying a high voltage to the discharge electrode 2 from an AC high-voltage power source 3 through a high-voltage cable 8 to generate positive and negative air ions. The discharge electrode 2 comprises a plurality of needle-like electrodes 6 arranged side by side in a horizontally-long tubular electrode case 4 formed of an insulation material in the longitudinal direction of the electrode case, and counter electrodes 7 arranged oppositely to the needle-like electrodes 6. The AC high-voltage power source 3 is composed by arranging, in a horizontally-long power source case 11, a winding transformer 9 with the high-voltage cable 8 connected to its secondary side, and a pulse generation circuit 10 applying pulse input to its primary side. The power source case 11 is superposed on the electrode case 4 to form both the cases integrally with each other, and the high-voltage case 8 is housed in both the cases. COPYRIGHT: (C)2009,JPO&INPIT
