To provide a coil unit for use in a non-contact power transmission system, in which the size of the coil unit is suppressed while the insulation distance of a capacitor is ensured.SOLUTION: Capacitor elements 105, 115, 125, 135 are connected in series, and the capacitor element 105 is connected to a coil. An insulating member 140B is provided between the capacitor elements 105, 115, 125, 135 and an upper cover 32 of a case 30. The height h1 of the capacitor element 105 is lower than the height h2 of each of the capacitor elements 115, 125, 135. The thickness H1 of the insulating member 140B between the capacitor element 105 and the upper cover 32 is thicker than the thickness H2 of the insulting member 140B between the capacitor elements 115, 125, 135 and the upper cover 32.SELECTED DRAWING: Figure 7
【課題】非接触の電力伝送システムに用いられるコイルユニットにおいて、キャパシタの絶縁距離を確保しつつコイルユニットのサイズを抑制する。【解決手段】キャパシタ素子105,115,125,135は直列接続され、キャパシタ素子105がコイルに接続される。絶縁部材140Bは、キャパシタ素子105,115,125,135とケース30のアッパーカバー32との間に設けられる。キャパシタ素子105の高さh1は、キャパシタ素子115,125,135の高さh2よりも低い。キャパシタ素子105とアッパーカバー32との間の絶縁部材140Bの厚みH1は、キャパシタ素子115,125,135とアッパーカバー32との間の絶縁部材140Bの厚みH2よりも厚い。【選択図】図7
