Zusammenfassung:	[Solving Means] An antenna resonance unit (110) includes an antenna coil (L1) and an impedance matching unit (114). A drive unit (e.g., antenna drive unit 130) generates a transmission signal with respect to the antenna resonance unit (110). A detection unit (106) detects a drive current or drive power for operating the drive unit. A control unit (140) is capable of generating a control signal for controlling the impedance matching unit (114), and controls a resonance frequency of the antenna resonance unit (110) using, out of the control signal, an optimal control value with which the drive current or drive power detected by the detection unit (106) becomes minimum.
