<p>A coil unit (12,22) includes a planar coil (30) that has a transmission side (31) and a non-transmission side (32), a magnetic sheet (40) provided over the non-transmission side of the planar coil, and a heat sink/magnetic shield plate (50,210) stacked on a side of the magnetic sheet opposite to a side that faces the planar coil, the heat sink/magnetic shield plate dissipating heat generated by the planar coil and shielding magnetism by absorbing a magnetic flux that has not been absorbed by the magnetic sheet. The heat sink/magnetic shield plate has a thickness larger than that of the magnetic sheet.</p> |
