To increase the versatility of a roadside device excluding a power transmission coil in a noncontact power supply system.SOLUTION: A roadside device for a noncontact power supply has a power transmission coil and a power transmission device and transmits electric power to a power reception coil in an electric vehicle by magnetic field resonance in a non-contact manner from the power transmission coil. Regardless of the size of the power transmission coil, an inductance and a coupling coefficient are designed such that a coefficient of a power transmission determined by the inductance of the power transmission coil and the coupling coefficient between the power transmission coil and the power reception coil is kept from changing from a certain value.SELECTED DRAWING: Figure 1

    【課題】非接触給電システムにおける、送電コイルを除く路側装置の汎用性を高める。【解決手段】送電コイル及び送電装置を有し、当該送電コイルから非接触で磁界共振により電動車両の受電コイルに送電する、非接触給電の路側装置であって、送電コイルの大きさに関わらず、送電コイルのインダクタンス及び送電コイルと受電コイルとの間の結合係数によって決まる電力伝送の係数が一定値から変化することを抑制するよう、インダクタンス及び結合係数が設計されている。【選択図】図1
