<P>PROBLEM TO BE SOLVED: To provide a non-contact type information medium structured especially to suppress decomposition using heat and unauthorized reuse in order to improve the false alternation preventing function of the non-contact type information medium. <P>SOLUTION: A non-contact type information medium is configured such that the adhesive force of an adhesive layer 14 between a conductor 12 patterned so as to be used as an antenna and an antenna base material sheet 11 is smaller than the adhesive force of an adhesive layer 23 between the conductor 12 and an exterior base material 21, and/or that the adhesive force of an adhesive layer 15 between a conductor 13 patterned so as to be used as a jumper line and the antenna base material sheet 11 is smaller than the adhesive force of an adhesive layer 24 between the conductor 13 and an exterior base material 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
