In an RFID (radio frequency identification) tag comprising an antenna formed of a conductive paste containing conductive filler like silver flakes on a base member, and an RFID chip connected to the antenna, the present invention cures a pattern of the antenna formed of the conductive paste, and then connects the RFID chip to the antenna with thermoplastic resin contained in the conductive paste by heating bump electrodes of the RFID chip in contact with the antenna. According to the present invention, Since the bump electrodes of the RFID chip and the antenna are connected to each other and establish sufficient electrical conduction therebetween without providing an anisotropic conductive sheet or the like therebetween, a highly reliable RFID tag is supplied at a low cost.
