PROBLEM TO BE SOLVED: To easily provide a non-contact data transmitter/receiver, which improves the capacitance of an antenna and controls the capacitance without newly designing the antenna. SOLUTION: A capacitance control means 3 having a conductor 8 of the same pattern as an antenna pattern in a part of an antenna 6 is adhered on an insulator 7 being overlapped on a substrate 4, a conductor 5 in a part of the antenna 6 and the conductor 8 of the capacitance control means 3 are arranged correspondently through an insulating material A, and the conductor 8 of the capacitance control means 3 and the antenna 6 are conducted. |
