Abstract
Provided is a method for manufacturing a wireless power-transmitting device including a power-transmitter having a transmission coil, and a power-receiver having a reception coil. The method includes forming, in the electrically-conductive member, an eddy current interruption unit configured to change a state of an eddy current, formed in the electrically-conductive member by the transmission coil (reception coil), by interrupting and redirecting a portion of the eddy current to obtain processed electrically-conductive members, and preparing a plurality of types of the processed electrically-conductive members whose eddy current interruption units are different in form from each other; and selecting one type of the processed electrically-conductive member from the plurality of types of the processed electrically-conductive members and arranging the selected one type of the processed electrically-conductive member near the transmission coil (reception coil), thereby finely adjusting the inductance of the transmission coil (reception coil) to reach a preset inductance.
