A charging amount detection device 13 is worn by a human body and measures the surface potential of the human body. A static electricity control device 12 is worn by a human body and generates and discharges ions to the human body and thereby controls the static electricity on the human body. A mobile terminal 11 sets a control pattern of the static electricity on the human body that is suitable for a condition such as temperature and humidity for the static electricity control device 12 via short-range wireless communication. The static electricity control device 12 uses the set control pattern to perform feedback control of the static electricity on the human body by using the surface potential of the human body measured by the charging amount detection device 13. ## Claims ### Claim 1 A human body static electricity control device that controls static electricity on a human body and has a structure that is wearable
