Abstract
A noncontact power-transmission coil is provided. The noncontact power-transmission coil includes a planar coil and a magnetic layer. The planar coil is formed by winding a linear conductor in a spiral shape substantially in a single plane. The magnetic layer is formed by applying a liquid-form magnetic solution in which magnetic particles are mixed with a binder solvent, so as to cover one planar portion of the planar coil and a side-face portion of the planar coil.
