Abstract

A noncontact ID card composed by laminating an antenna circuit board where an antenna is formed and an interposer board formed by connecting an enlarged electrode to an electrode of a mounted IC chip and bonding between an antenna electrode of the antenna circuit board and the enlarged electrode of the interposer board with electroconductive adhesive material, wherein a substrate of the antenna circuit board and a substrate of the interposer board are bonded. In addition, in another composition, at least one local deformation is applied to a boding face of the electrodes each other in a direction crossing the bonding face.
