An object is to reduce troubles during pressure bonding of an antenna in a
wireless chip including a thin film. A wireless chip made from a thin
film is formed, in particular a wireless chip including a memory area
including an organic compound layer, and a distance between the memory
area and a pad is a prescribed value or longer. As a result, data writing
can be carried out without being affected by stress or heat during
pressure bonding of the antenna. For a substrate over which the wireless
chip is provided, a glass substrate or a silicon wafer can be used.
