Claim Text:
1. A magnetic element for wireless power transmission, which generates an induced electromotive force, comprising: a conductor portion through which an alternating current flows; and a magnetic part arranged in parallel to the conductor portion, wherein the magnetic part includes a resin in which magnetic particles are dispersed, and the conductor portion is at least partially bonded and integrated with the magnetic part, while being electrically insulated therefrom, by the resin, and wherein the magnetic particles are either spherical particles or flat particles, when the magnetic particles are spherical particles, the spherical magnetic particles with a mean grain diameter of 1 μm to 300 μm are mixed into the resin for an amount of 50 Vol % to 90 Vol % with respect to the resin, and when the magnetic particles are flat particles, the flat magnetic particles with a grain diameter of not more than 50 μm and with an aspect ratio of 10 or higher are mixed into the resin for an amount of 20 Vol % to 70 Vol % with respect to the resin.
