<P>PROBLEM TO BE SOLVED: To provide an IC tag having a pressure-sensitive function for visually recognizing a pressure to be applied on an IC tag. <P>SOLUTION: In this IC tag 1 configured of a multi-layer structure in which an inlet 25 including an IC chip 15, an antenna pattern 11 or the like as the primary section of the IC tag 1 on one face of a base film 29 and upper paper 21 are stuck together by adhesive layers 27 and 23, a pressure-sensitive layer 47 is formed between the inlet 25 and the upper paper 21. The pressure-sensitive layer 47 is a pressure measurement film configured of a coloring agent layer 41 and a color developer layer 43 to perform coloring according to a pressure. The pressure-sensitive layer 47 may be formed on the whole face of the IC tag 1, or only the peripheral section of the IC chip 15 in the IC tag 1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
