PROBLEM TO BE SOLVED: To provide a control device, an electronic apparatus, a contactless power transmission system, and the like that can improve resistance to noise or the like in the detection of load fluctuation caused by load modulation.SOLUTION: A power transmission side control device in a contactless power transmission system includes: a driver control circuit 22 for controlling a power transmission driver of a power transmission unit 12; a control unit for controlling the driver control circuit 22; and a communication unit 30 for performing a communication process with a power reception device that transmits communication data by load modulation. The communication unit 30 detects the communication data from the power reception device on the basis of output from a bandpass filter unit 33 that performs a bandpass filter process of letting a signal in a frequency band for load modulation pass and attenuating a signal in a band other than the frequency band for load modulation.SELECTED DRAWING: Figure 5 |
