A contactless charging system using a capacity coupling scheme is provided to prevent a discharging accident due to a contact with a foreign substance by not exposing a power terminal of a portable device to an outside. A contactless charging system using a capacity coupling scheme includes a power supply(300), and a portable device(200) having a charger(220), and a rectifier(210). The power supply(300) applies an AC power to a single power side flat conductor. The charger(220) charges a DC power and has a single load side flat conductor opposite to the single power side flat conductor. The rectifier(210) rectifies a voltage change of the single load side flat conductor for a ground voltage of the charger(220). The rectifier(210) applies the rectified voltage to the charger(220). A side or both sides of the single power side flat conductor and the single load side flat conductor are covered with an insulation protection film having a dielectric constant, and are charged by a capacity coupling scheme.
