Abstract
A base sheethas a structure that stably couples a particular chip measuring 1 mm or less on paper with an antenna line by only disposing the chip and antenna line in such a manner that the chip and antenna line are close to each other, without electrically bringing the chip and antenna line into contact with each other. The base sheetincludes a chiphaving a spiral coilwith at least one turn disposed on a surface of the chip, or inside the chip and near the surface thereof and an antenna linehaving a conductor partA orbiting around the coilA of the chipor directly over or directly below the coilA so that the conductor part is magnetically coupled with the coilA. This base sheet has a structure that stably couples even a chip measuring 1 mm or less on paper or the like with an antenna line by only disposing the chip and antenna line in such a manner that the chip and antenna line are close to each other, without physically bringing the chip and antenna line into contact with each other.
