<P>PROBLEM TO BE SOLVED: To provide a non-contact IC medium wherein an antenna is surely destroyed if an IC inlet of the non-contact IC medium packaged between external layer base materials is to be intentionally peeled off. <P>SOLUTION: The non-contact IC medium is constituted of packaging an IC chip 41 in which unique identification information is stored and a combined antenna 30 constituted of an antenna 31 made of conductive paste and an antenna 32 made of a metal or an alloy between external layer base materials 11, 12 made of paper or weak base materials through an adhesive layer 20a comprising an adhesive layer 21a having non-adhesive patterns 21a<SB>1</SB>, 21a<SB>2</SB>, 21a<SB>3</SB>, 21a<SB>4</SB>and an adhesive layer 22a having non-adhesive patterns 22a<SB>1</SB>, 22a<SB>2</SB>, 22a<SB>3</SB>, 22a<SB>4</SB>. <P>COPYRIGHT: (C)2008,JPO&INPIT |
