Summary:To prevent proper communication from being disrupted during power transmission.SOLUTION: A power receiving device includes power receiving means for receiving power wirelessly from a power transmission device, communicating means for communicating with the power transmission device by load modulating the power received by the power receiving means, and control means for controlling the modulation of the load modulation by the communication means so that the modulation level of the load modulation is changed when no response signal from the power transmission device for a predetermined signal transmitted by the communication means is received within a predetermined time.SELECTED DRAWING: Figure 2 【課題】送電中において適切な通信が行われなくなることを抑制する。【解決手段】受電装置は、送電装置から無線で電力を受電する受電手段と、前記受電手段により受電される電力を負荷変調することにより、前記送電装置と通信を行う通信手段と、前記通信手段により送信された所定の信号に対する前記送電装置からの応答信号が所定の時間内に受信されない場合、前記通信手段による負荷変調の変調度が変更されるように制御する制御手段とを有する。【選択図】図２
