摘要

Provided are a planar coil that can inhibit eddy-current loss thereof, and a coil module, power reception apparatus and contactless power transmission apparatus provided with same. A secondary coil is a planar coil provided with first and second conductor wires wound in a planar form, the first and second conductor wires are rectangular wires (43A, 43B) having rectangular cross sections, and the rectangular wires (43A, 43B) have a plurality of notches (45) that are formed on the upper faces (46A, 46B) thereof and extend in the extending direction of the rectangular wires (43A, 43B).
