Abstract
A coil unit includes a coil and a core member. The coil receives AC electric power transmitted in a contactless manner from an electric power transmission apparatus. The core member is formed of a directional magnetic material in sheet form. The core member is arranged on a rearward side of the coil when seen from the electric power transmission apparatus when the electric power transmission apparatus and the coil face each other. An outer shape of each of the coil and the core member is a rectangular annular shape. An orientation direction of the core member and a direction along a winding direction of the coil are orthogonal to each other in straight line portions that face each other of the coil and the core member.
Claims3
A coil unit, comprising:
- a coil that receives AC electric power transmitted in a contactless manner from an electric power transmission apparatus;
- and
- a core member that is formed of a directional magnetic material in a sheet form and is arranged on a rearward side of the coil when seen from the electric power transmission apparatus when the electric power transmission apparatus and the coil face each other,
- wherein a magnetization direction of the core member is aligned in an orientation direction by the core member being formed of the directional magnetic material, and the orientation direction of the core member is orthogonal to a direction along a winding direction of the coil.
