Abstract
A transmission/reception antenna () comprises a core () and a coil () wound around the core (). One of a plurality of core sheets () constituting the core () is utilized as a sensor electrode (). Conductors () extending from the two ends of the coil () are connected to a transmission/reception drive circuit (). The conductor () extending from a capacitance detector () is connected to one of the conductors () extending between the coil () and the transmission/reception drive circuit (). Consequently, the capacitance detector () is alternately connected to the sensor electrode () through a parasitic capacitance Cgenerated between the coil () and the sensor electrode () (core sheet ()).
