The invention provides a coil unit capable of suppressing an increase in weight and improving cooling efficiency. A coil unit for a vehicle is provided with: a housing (11); a coil (13) that acquires AC power transmitted in a non-contact manner from the power transmission device (T); and a support member (31). The housing (11) has a surface (11A) exposed to the outside below the vehicle body. A coil (13) disposed inside the housing (11) is in direct contact with the housing (11) via a heat dissipation member (11b) provided on the inner surface (11B) of the housing (11). The support member (31) is in contact with the inner surface (11B) of the housing (11) and the heat dissipation member (11b), and covers the surface of the coil (13). The width of the support member (31) in the direction orthogonal to the direction in which the heat dissipation member (11b) protrudes changes in an increasing tendency from the tip side of the heat dissipation member (11b) toward the inner surface (11B) in the direction in which the heat dissipation member (11b) protrudes.

    本发明提供能抑制重量的增大且提高冷却效率的线圈单元。车辆用线圈单元具备:壳体(11);线圈(13),其获取从送电装置(T)以非接触方式传送的交流电力;支承构件(31)。壳体(11)具有向车身下方的外部露出的表面(11A)。配置于壳体(11)的内部的线圈(13)经由设置于壳体(11)的内表面(11B)的散热构件(11b)而与壳体(11)直接接触。支承构件(31)与壳体(11)的内表面(11B)及散热构件(11b)接触,并且覆盖线圈(13)的表面。支承构件(31)在散热构件(11b)的突出方向的正交方向上的宽度伴随沿着突出方向从散热构件(11b)的顶端侧趋向内表面(11B)而呈增大倾向变化。
