Abstract
An antenna device includes a sensor electrode having a capacitance configured to change upon an object approaching or contacting the sensor electrode, a sensor circuit electrically connected to the sensor electrode, an antenna section, and a substrate having the sensor circuit mounted thereon and having the sensor electrode fixed thereto. The sensor circuit is configured to detect the capacitance. The substrate is inserted into the antenna section. This antenna device allows components to be easily positioned during assembly.
