POWER TRANSMISSION APPARATUS
First Claim
1. A power transmission apparatus comprising:
- a cover part attached to one of a power transmitter and an electronic apparatus, the power transmitter including a primary-side coil connected to an alternating-current power supply and a primary-side resonant coil configured to receive power from the primary-side coil by electromagnetic induction, the electronic apparatus including a secondary-side coil; and
a secondary-side resonant coil disposed in the cover part, and configured to transmit to the secondary-side coil the power received from the primary-side resonant coil by magnetic field resonance generated between the primary-side resonant coil and the secondary-side resonant coil.
