PROBLEM TO BE SOLVED: To provide a control device, an electronic apparatus, a contactless power transmission system, and the like that can improve detection sensitivity of load fluctuation caused by load modulation and detection resistance to noise.SOLUTION: A power transmission side control device in a contactless power transmission system includes: a driver control circuit for controlling a power transmission driver of a power transmission unit; a control unit for controlling the driver control circuit; and a communication unit for performing a communication process with a power reception device that transmits communication data by load modulation. The communication unit determines the communication data is at a first logic level if a load modulation pattern comprised of a first load state and a second load state is a first pattern (PT1), and determines the communication data is at a second logic level if the load modulation pattern is a second pattern (PT2) different from the first pattern.SELECTED DRAWING: Figure 9 |
