<P>PROBLEM TO BE SOLVED: To increase the durability and treatability of an IC tag with respect to an IC housing case in which an IC tag is stored. <P>SOLUTION: A supporting wall 14 constituted of heat insulating materials is supported on the internal face of a case body 13 shaped like a regular tetrahedron, and the IC tag 11 is supported on the supporting wall 14 so that the IC tag 11 can hardly enter a narrow clearance, and that its stability and treatability can be improved even when it is set in any attitude. Also, its durability to any impact can be increased compared with the case that the IC tag 11 is peeled for use, and its thermal resistivity can be increased by making it difficult to transfer heat from the case body 13 to the IC tag 11. Especially, the supporting wall 14 is configured of a plate body passing the two vertexes of the case body 13 and the middle points of sides which do not pass those vertexes, and the thermal resistivity of the IC tag 11 can be further increased by supporting the IC tag 11 at the central part of the case body 13. Furthermore, an antenna part 16 is exposed from the vertexes of the case body 13 to the outside so that any probability that the antenna part 16 is held under the case body 13 can be decreased, and that communication sensitivity can be secured. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
