Summary:To minimize a time during which a specific user occupies a resource of a wireless power feeding device when a mobile terminal device is wirelessly powered, and to facilitate sharing of the resource by a plurality of users.SOLUTION: In a wireless power feeding system 1 in which a master mobile terminal device A0 transmits wireless power feeding radio waves 41 and 42 to at least one or more slave mobile terminal devices A1 and A2 that operate according to control from a mobile terminal device to feed power, the master mobile terminal device includes: an inter-apparatus communication apparatus that receives a power feeding request signal from a slave mobile terminal device to the slave mobile terminal device through inter-apparatus communications 31 and 32; a power transmitting control circuit that transmits power to the slave mobile terminal device; a battery; and a control device that controls the operation of the inter-apparatus communication apparatus and the power transmitting control circuit. When the inter-apparatus communication apparatus receives the power feeding request signal, the control device detects a remaining battery level, and controls the power transmitting control circuit and the inter-apparatus communication apparatus to output electromagnetic waves for wireless power feeding according to a detection result of the remaining battery level.SELECTED DRAWING: Figure 1 【課題】携帯端末装置に対して無線給電をする際に、無線給電装置のリソースが特定ユーザに占有される時間をなるべく少なくし、リソースを複数人で共用しやすくする。【解決手段】主携帯端末装置Ａ０から、携帯端末装置からの制御に応じて動作する少なくとも１つ以上の従属携帯端末装置Ａ１、Ａ２に対して無線給電電波４１、４２を送信して給電する無線給電システム１において、主携帯端末装置は、従属携帯端末装置から、機器間通信３１、３２で従属携帯端末装置に対する給電要求信号を受信する機器間通信機と、従属携帯端末装置に対して送電する送電制御回路と、バッテリと、機器間通信機及び送電制御回路の動作を制御する制御装置と、を備え、機器間通信機が給電要求信号を受信すると、制御装置はバッテリ残量を検出し、バッテリ残量の検出結果に応じて送電制御回路及び機器間通信機に対して無線給電のための電磁波を出力させるための制御を行う。【選択図】図１
