Abstract:
It is an object of the present invention to provide a wireless chip of which mechanical strength can be increased. Moreover, it is an object of the present invention to provide a wireless chip which can prevent an electric wave from being blocked. The invention is a wireless chip in which a layer having a thin film transistor is fixed to an antenna by an anisotropic conductive adhesive or a conductive layer, and the thin film transistor is connected to the antenna. The antenna has a dielectric layer, a first conductive layer, and a second conductive layer. The dielectric layer is sandwiched between the first conductive layer and the second conductive layer. The first conductive layer serves as a radiating electrode and the second conductive layer serves as a ground contact body.
