Provided is a communication device including a first communication unit for performing communication by a communication scheme, the communication scheme being for applying voltage from a signal electrode that is in contact with or that is brought into proximity of a human body, generating an electric near field on a human body surface and performing transmission, a second communication unit different from the first communication unit, a switching signal detection unit for detecting, from signals intermittently received by the first communication unit, a mode switching signal for switching the second communication unit from a power save mode to a normal mode, and a switching control unit for switching the second communication unit from the power save mode to the normal mode in a case the mode switching signal is detected by the switching signal detection unit.
