SOLUTION: A data carrier is provided with an ID module 23 as a coil module 24 as a data carrier main body part. The coil module 24 is provided with a coil L2-1 which is electromagnetically coupled with the coil of the ID module 23 and a coil L2-2 which is electromagnetically coupled with a read/write head. Both ends of L2-1 and L2-2 of those coils are connected to each other. Then the coil L2-2 is formed in various shapes and a communication with the read/write head is made easy.
