PROBLEM TO BE SOLVED: To provide an ion generator capable of efficiently generating ions with simple constitution while greatly reducing generation of ozone by using an electron emission system.SOLUTION: An ion generator 1 according to the present invention comprises an electron emission element 10. Further, the ion generator 1 comprises a control electrode 15 arranged apart from the electron emission element 10 across a space, and applies a voltage to the control electrode 15 so as to control the amount of electrons emitted from the electron emission element 10.SELECTED DRAWING: Figure 2A |
