1. A human body static electricity control device that controls static electricity on a human body and has a structure that is wearable on the human body, the human body static electricity control device comprising:
an ion generation unit that generates ions;
an ion discharge unit that discharges the ions generated by the ion generation unit to the human body in a first state where the human body static electricity control device is worn by the human body; and
a control unit that controls an ion generation operation in the ion generation unit,
wherein the ion generation unit is capable of generating positive ions and negative ions, and
wherein the control unit causes the ion generation unit to generate the positive ions and the negative ions such that a positive potential and a negative potential alternately occur at a predetermined frequency as a surface potential of the human body.
