PROBLEM TO BE SOLVED: To provide a power transmission relay device which allows for efficient power supply from a power transmission coil to a power reception coil included in an electronic product, by interposing between the power transmission coil and power reception coil, even though the distance therebetween is far away, when charging the electronic product.SOLUTION: In a power transmission relay device, a mobile device 1 moving between a power transmission coil 7 and a power reception coil 8, and the relay coil body 2b of a relay coil l2 fixed to the mobile device 1 are arranged so that a distance allowing appropriate resonance with a magnetic field generated in the power transmission coil body 7b of the power transmission coil 7 is ensured for any position of the surface. When a current flows through the relay coil body 2b of a relay coil l2, and a magnetic field generated by the current and the power reception coil body 8b of the power reception coil 8 resonate, power is supplied efficiently from the power transmission coil body 7b to the power reception coil body 8b.SELECTED DRAWING: Figure 1 【課題】電子製品の充電を行う際、送電用コイルと受電用コイルの間の距離が離れていても、送電用コイルと受電用コイルの間に介入して送電用コイルから電子製品に備えられた受電用コイルに電力を効率良く供給することを可能とする電力伝送中継装置を提供する。【解決手段】電力伝送中継装置は、送電用コイル７と受電用コイル８の間まで移動する移動装置１と該移動装置１に固設された中継コイル２の中継コイル本体２ｂが、その面のどの位置に対しても前記送電用コイル７の送電用コイル本体７ｂで発生する磁界と適切に共振できる距離になるように配置され、中継コイル２の中継コイル本体２ｂに電流が流れ、流れた電流で起こる磁界と前記受電用コイルの受電用コイル本体８ｂが共振することにより、前記送電用コイル本体７ｂから前記受電用コイル本体８ｂに効率良く電力を供給させる電力伝送中継部を備える。【選択図】図１
