A communication device includes a ground unit, a dielectric plate, a communication circuit, a conductor, and a capacitance element. The ground unit has a reference potential applied to the ground unit. The dielectric plate is provided on the ground unit. The communication circuit is provided on the dielectric plate and performs a transmission and a reception of a signal. The conductor is connected to the communication circuit. An end of the capacitance element is connected to the conductor. An another end of the capacitance element is connected to the ground unit. A capacitance of the capacitance element is smaller than a capacitance formed between the conductor and the ground unit. The capacitance of the capacitance element is bigger than a capacitance formed between the conductor and the ground unit being caused by a human body touching or approximating to the conductor. |
