PROBLEM TO BE SOLVED: To provide a transmission apparatus with high charging efficiency by suppressing an adverse effect of mutual inductance between two transmission coils conforming to different standards.SOLUTION: A transmission apparatus 100 includes a transmission circuit 41 for generating an electric signal; a first transmission coil 10 for transmitting electric power by means of a first transmission system with an electric signal generated by the transmission circuit; and a second transmission coil 20 for transmitting electric power by means of a second transmission system with an electric signal generated by the transmission circuit. The transmission circuit, when generating an electric signal to transmit electric power from the second transmission coil, generates the electric signal to the fist transmission coil so that an electric current flows in an opposite direction to a flowing direction of an electric current generated by interlinking a magnetic flux generated from the second transmission coil to the first transmission coil.SELECTED DRAWING: Figure 2 【課題】 異なる規格に準拠する２つの送電コイルにおける相互インダクタンスの影響を低減させて、充電効率の良い送電装置を提供する。【解決手段】 送電装置１００は、電気信号を生成する送電回路４１と、送電回路が生成する電気信号により第１の伝送方式で電力を伝送する第１送電コイル１０と、送電回路が生成する電気信号により第２の伝送方式で電力を伝送する第２送電コイル２０と、を備え、送電回路は、第２送電コイルから電力を伝送するように電気信号を生成する場合に、第２送電コイルから発生する磁束が第１送電コイルに鎖交することにより発生する電流の流れる方向と逆向きの方向に電流を流すように第１送電コイルに対して電気信号を生成する。【選択図】 図２
