Abstract
A coil unit for contactless power transmission includes a non-circular flat coil; a core member made of a magnetic material; and a thermal conductor that has a higher thermal conductivity than the core member. The coil has a corner section and a non-corner section in a coil axial direction view, and the core member and the thermal conductor are disposed to face the non-corner section and the corner section, respectively in a coil axial direction.
