摘要 |
<p>A coil unit (12,22) includes a planar coil (30), a magnetic member (52) that is provided under the planar coil, a magnetic flux leakage prevention member (54) that is provided under the magnetic member, and a heat sink (70) that is provided under the magnetic flux leakage prevention member. The magnetic flux leakage prevention member is electrically insulated from the heat sink. The magnetic flux leakage prevention member is insulated from the heat sink using a double-sided adhesive tape (60), for example. Since the heat sink dissipates heat generated from the planar coil and is electrically insulated from the magnetic flux leakage prevention member, the heat sink does not function as a member which receives a magnetic flux.</p> |
