Abstract
A radio communication device is obtained which is provided with an RFID tag function which can ensure the mounting area of each antenna as large as possible, and which is sharable with an LF band RFID system or an HF band RFID system and a UHF band RFID system, while having a communication range equivalent to the communication range of each of an LF band an HF band and a UHF band. The device is provided with an integrated circuit () having a communication function in a first frequency band, a conductive object () connected to one of input and output terminals of the integrated circuit (), an integrated circuit () having a communication function in a second frequency band, and a second conductive object connected between input and output terminals of the integrated circuit (). The second conductive object is composed of a spiral conductive object (). The other of the input output terminals of the integrated circuit () is connected to a part of the spirally wound conductive object ().
