To more surely remove a foreign matter.SOLUTION: A foreign matter removal device 20 is a foreign matter removal device 20 used by a coil device 10 for non-contact power supply, and includes: a body including a surface 26a arranged on a power transmission coil C2 included in the coil device 10, and a plurality of fluid ejection holes H respectively provided with openings Ha at positions different from one another on the surface 26a; and a removal part 30 connected to the plurality of fluid ejection holes H to eject fluid F from each of the openings Ha. The removal part 30 includes: a plurality of valves 33 provided respectively corresponding to the plurality of fluid ejection holes H to make the fluid F flowing through the openings Ha to flow out; and a plurality of sensors 34 provided on flow channels for connecting the valves 33 to the openings Ha respectively to detect the flow rates or pressures of the fluid F flowing through the flow channels as detection values for determining whether a foreign matter M exists on the surface 26a.SELECTED DRAWING: Figure 2

    【課題】異物の除去をより確実に行う。【解決手段】異物除去装置20は、非接触給電のためのコイル装置10に用いられる異物除去装置20であって、コイル装置10が備える送電コイルC2上に配置された表面26a、及び、表面26aの互いに異なる位置に開口Haがそれぞれ設けられた複数の流体噴出孔Hを含む本体と、複数の流体噴出孔Hに接続されており、各開口Haから流体Fを噴出させる除去部30と、を備え、除去部30は、複数の流体噴出孔Hにそれぞれ対応して設けられており、各開口Haに流れる流体Fを流出させる複数のバルブ33と、各開口Haに各バルブ33を接続する各流路上に設けられており、各流路を流れる流体Fの流量又は圧力を、表面26a上に異物Mが存在するか否かを判定するための検出値としてそれぞれ検出する複数のセンサ34と、を含む。【選択図】図2
