To enable reliable transmission of power from a power transmission unit of a power transmission device to a power reception unit of a power reception device.SOLUTION: A power transmission device (100) includes a first coil (122) that outputs power to a power reception unit (210) of a power reception device (200) in a non-contact manner, a plurality of second coils (121) that supply power from a power source to the first coil (122) in a non-contact manner, and a control unit (130) that sets an initial position for the first coil (122) in a state where the power reception unit (210) is positioned outside the arrangement range of the second coils (121), and moves the first coil (122) to the initial position.SELECTED DRAWING: Figure 1

    【課題】送電装置の送電部から受電装置の受電部へ確実に電力を伝送することができるようにすること。【解決手段】受電装置(200)の受電部(210)へ非接触で電力を出力する第1のコイル(122)と、電源からの電力を第1のコイル(122)へ非接触で供給する複数の第2のコイル(121)と、受電部(210)が第2のコイル(121)の配設範囲外に位置している状態で、第1のコイル(122)の初期位置を設定し、第1のコイル(122)を初期位置へ移動させる制御部(130)と、を備える、送電装置(100)。【選択図】図1
