Abstract:
A foldable sheet having a rectangular sheet surface, and mounted thereon with an electric circuit having a planar electronic circuit chip, a planar capacitor and an antenna, characterized in that the planar surface of the capacitor has a size which is slightly smaller than that of each of rectangular areas which are obtained by sectioning the sheet surface by nÃ—m (where n and m are integers larger than 2), andthe capacitor, the electronic circuit chip and the antenna are mounted on the sheet so that the planar surface of the capacitor and a planar surface of the electronic circuit chip are in parallel with the sheet surface, the planar surface of the capacitor is accommodated within one of the rectangular areas obtained by sectioning the sheet surface by nÃ—m, as viewed in a direction perpendicular to the sheet surface, and the planar surface of the electronic circuit chip and the contour of the antenna are accommodated within the planar surface of the capacitor as viewed in a direction perpendicular to the sheet surface.
