PROBLEM TO BE SOLVED: To provide a tire pressure detecting device capable of making a monitoring device having a small number of receiving antennas receive the data showing a tire condition properly even if the transmission intensity is weak and reducing the cost of the monitoring device. SOLUTION: A receiving circuit 17 and a transmitting circuit 18 are arranged in sensor devices 14a to 14f, and the data received from other sensor devices 14a to 14f through the receiving circuit 17 are transferred through the transmitting circuit 18 by a CPU 25. Even if the data detected by any of the sensor devices 14a to 14f do not reach the monitoring device, therefore, the data detected by the sensor devices 14a to 14f are transferred by any one of or a plurality of sensor devices 14a to 14f and received by the monitoring device.
