PROBLEM TO BE SOLVED: To prepare a contactless IC card capable of reduced man-hours, satisfactory in productivity and reduced cost. SOLUTION: This contactless IC card has a flexible substrate, where a spiral antenna coil and a circuit pattern are formed and a circuit module formed by connecting an IC chip to the circuit pattern and sends and receives information to and from external equipment through the antenna coil, and a cut part is formed at the periphery of the inner peripheral side end part of the spiral antenna coil, formed on the flexible substrate and the inner peripheral side end part of the antenna coil is folded back together, with the flexible substrate from the cut part and connected to the circuit pattern provided on the outer peripheral side of the antenna coil. |
