PROBLEM TO BE SOLVED: To provide a contactless data receiver/transmitter which prevents an antenna from being disconnected due to expansion and contraction of an article when using the antenna by embedding the antenna in the article to be an object, and which is excellent in mechanical strength of the antenna.SOLUTION: A contactless data receiver/transmitter 10 comprises: a substrate 11; an IC chip 12 and a first antenna part 13 disposed on one face 11a of the substrate 11 and electrically connected each other; an insulation part 14 made of insulation resin covering the IC chip 12 and the vicinity thereof; and second antennas 15 and 16 disposed so as to overlapping with a part of the first antenna 13 and made of conductive resin. The conductive resin and the insulation resin contain rubber as main material. |
