<p>A coil unit and a manufacturing method thereof, and an electronic device are provided to discharge heat of a planar coil by interposing a magnetic member and a magnetic flux leakage preventing member between a planar coil and a heat discharging plate without a space. A coil unit includes a planar coil(30), a magnetic member(52), a magnetic flux leakage preventing member(54), and a heat discharging plate(70). The magnetic member is installed under the planar coil. The magnetic flux leakage preventing member is installed under the magnetic member. The heat discharging plate is installed under the magnetic flux leakage preventing member. A both-sided adhesive tape(60) electrically insulates the magnetic flux leakage preventing member and the heat discharging plate from each other. The coil unit further includes a printed circuit board(80). The printed circuit board mounts the heat discharging plate thereon and has a conductive pattern connected to the planar coil.</p> |
