Title:
COIL UNIT
Document Type and Number:
WIPO Patent Application WO/2016/157773
Kind Code:
A1
Abstract:
This coil unit is provided with a coil, and a second conductive member, which is disposed between the coil and a first conductive member disposed close to the coil, said first conductive member having conducting properties, and which suppresses a coil impedance change due to the first conductive member, said second conductive member having conducting properties. Consequently, the coil impedance change that occurs when the coil is brought close to a member that increases the impedance can be suppressed, thereby making it possible to reduce the impedance even if a distance between the first conductive member, i.e., the coil installation surface, and the coil is not ensured, and reducing the coil installation height.
