摘要：There is provided a bidirectional transmission coil capable of miniaturizing astructure and carrying out reliable transmission of a data signal. A transmitting coil L

generates a magnetic flux of a transmission signal by a high frequency signal appliedthereto. A receiving coil L is arranged to be positioned concentrically with the

transmitting coil L, for inducing a reception signal by the magnetic flux from outside. Afirst cancel coil Lac is connected to the transmitting coil L in series so as to be led-outfrom a middle of the transmitting coil L and is led-in to the lead-out part. The first cancelcoil Lac is arranged so as to sandwich the receiving coil L between the first cancel coil Lacand the transmitting coil L, wherein the magnetic flux in a direction opposite to themagnetic flux from the transmitting coil L is generated in the receiving coil L
