To provide a wireless power receiving device capable of easily matching a relative distance of a power receiving coil with respect to a power transmitting coil to a desired distance.SOLUTION: A wireless power receiving device that receives AC power from a power transmission coil included in a wireless power transmission device includes: a power receiving coil that receives the AC power from the power transmission coil; a power receiving side imaging unit with an autofocus function; and a control unit that outputs relative distance information indicating the relative distance of the power receiving coil to the power transmission coil on the basis of a detection distance detected by the autofocus function used by the power receiving side imaging unit in imaging the marker when the power receiving side imaging unit captures a range that can be imaged by the power receiving side imaging unit and the marker located at a predetermined first position on the outer surface of the wireless power transmission device is imaged by the power receiving side imaging unit.SELECTED DRAWING: Figure 2

    【課題】送電コイルに対する受電コイルの相対的な距離を所望の距離へ容易に一致させることができるワイヤレス受電装置を提供する。【解決手段】ワイヤレス送電装置が備える送電コイルから交流電力を受電するワイヤレス受電装置であって、前記送電コイルから前記交流電力を受電する受電コイルと、オートフォーカス機能を有する受電側撮像部と、前記受電側撮像部が撮像可能な範囲を前記受電側撮像部に撮像させ、前記ワイヤレス送電装置の外表面における所定の第1位置に位置するマーカーが前記受電側撮像部により撮像された場合、前記受電側撮像部が前記マーカーの撮像において用いた前記オートフォーカス機能により検出された検出距離に基づいて、前記送電コイルに対する前記受電コイルの相対的な距離を示す相対距離情報を出力する制御部と、を備えるワイヤレス受電装置。【選択図】図2
