<p>A communication apparatus includes: a communication unit COM that performs operation control of a function involving transmission or reception of an electromagnetic wave by an antenna; a touch sensor module TSM having an oscillation circuit and an electrode connected to the oscillation circuit; a power supply PS that supplies power to the oscillation circuit; and a power supply controller PSCON that controls supply of power by the power supply PS. The touch sensor module TSM detects a contact operation based on an oscillation state of the oscillation circuit which varies in accordance with a contact operation. As a result, a state where the power supply PS is supplying power to the oscillation circuit under the control of the power supply controller PSCON and a state where the communication unit COM is performing operation control of the function involving transmission or reception of an electromagnetic wave do not exist concurrently.</p> |
