To provide a non-contact IC card, a non-contact IC card transmission medium, and their manufacturing method reducing the manufacturing cost and visually improving the appearance.
This non-contact IC card 10 is provided with a substrate 13, an IC chip 111 provided in the rear surface of the substrate 13, and first and second antenna parts 121 and 122 printed with ink containing a conductive material and mediating the communication between the IC chip 111 and an external reader/writer by an electrostatic coupling system in the rear surface. This non-contact IC card 10 is characterized in having a dummy pattern 14 formed in the rear surface so as to be overlapped with parts or all of the first and/or the second antenna part 121 and/or 122 and improving the external appearance of the first and/or the second antenna part 121 and/or 122.
