<P>PROBLEM TO BE SOLVED: To provide a minus ion generator which stably generates minus ion even when humidity is low. <P>SOLUTION: An electrode 7 is provided in a air passage 2 near an air blow- out port 4 of a frame 1 from which air of a air blower fan 5 is blown out, and a conductive member 8 mounted in the state insulated from a member in contact within the frame 1 separated from the electrode 7 is arranged. In the frame 1, high-voltage terminals 6b and 6c putting out a direct-current high voltage by a high-voltage transformer 6 and a rectification circuit 6a is provided, the minus high-voltage terminal 6b is connected to the electrode 7, the plus high-voltage terminal 6c is connected to the conductive member 8, and minus ion is generated by applying a direct-current high voltage between the electrode 7 and the conductive member 8. A humidification chamber 9 is provided surrounding a wall of the pair passage 2 outside the air passage 2, a lower part of the humidification chamber 9 is provided with a humidification water tank 10 for reserving water for humidification and a humidification means for evaporating the water in the humidification water tank 10, and by filling inside the humidification chamber 9 with steam generated by the humidification means 11, electric charge of the frame 1 is prevented. <P>COPYRIGHT: (C)2004,JPO |
