Document Type and Number:
WIPO Patent Application WO/2015/189977
Kind Code:
A1
Abstract:
[Problem] To provide an inductor for wireless power transmission, for which stress applied to a magnetic core is mitigated. [Solution] An inductor according to one embodiment is provided with a magnetic core, a case, a coil, and a resin. The case accommodates therein the magnetic core. The coil is wound around the case. The resin is formed of a first resin so as to cover the case and the coil. The difference between the inner dimensions of the case and the dimensions of the magnetic core, in the same directions, is greater than the amount of change in the dimensions of the case in such directions when forming the resin.
