Since a power source voltage is generated from a communication signal in a wireless chip, there is a risk that a large amount of voltage be generated in the wireless chip to electrically destroy a circuit in the case of supplying a strong communication signal. Therefore, the present invention is made with an aim to provide a wireless chip having resistance to a strong communication signal. A wireless chip of the present invention has an element in which a power source wire and a grounding wire are electrically short-circuited if a power source voltage exceeds a voltage at which an electric circuit is destroyed, i.e., exceeds the specified voltage range. Accordingly, a wireless chip of the present invention has resistance to a strong communication signal.
