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.
