To provide portable ion generating equipment with a discharging means 12 in a predetermined case body 10 for generating negative ions which are blown off from an ion release port 24 to the outside of the case body 10, having the improved efficiency of supplying the negative ions to hairs while maintaining a simple construction.

In the case body 10, there are provided the discharge electrode 16 for generating the negative ions with negative-polarity high voltages applied thereto, and a blowing means 30. The high voltage is intermittently applied to the discharge electrode 16, and a discharge halting period is changed corresponding to a magnitude of a blowing amount of the blowing means 30.
