<P>PROBLEM TO BE SOLVED: To eliminate a printing impossible area due to irregularities on a surface or a back surface of an RFID tag on whose surface or back surface which printing is performed. <P>SOLUTION: An RFID tag includes a base film, an antenna pattern formed on the base film, an IC chip solder-connected to the antenna pattern, an insulating film layer formed on the antenna pattern, an underfill material filled in a gap between the IC chip and the antenna pattern/the base film and a gap between the IC chip and the insulating film layer, a forming layer which is bonded to the insulating film layer and has a window at a part corresponding to an upper surface of the IC chip so that a height of a surface of the forming layer is substantially equal to a height of a surface of the IC chip, a shock-absorbing layer filled in a gap between the forming layer and the base film/the IC chip, and a printing layer covering the surface of the forming layer and the IC chip. <P>COPYRIGHT: (C)2012,JPO&INPIT |
