A module for wireless power transmission in a magnetic resonance mode is provided. The module for wireless power transmission in a magnetic resonance mode according to one embodiment of the present invention, which is provided with a radiator for wireless power transmission disposed adjacently to a conductor, comprises: a radiator unit comprising the radiator for wireless power transmission; and a magnetic shielding unit disposed on one side of the radiator unit and provided with a magnetic shielding layer, which comprises fragments of an Fe-based alloy, which have been fragmented so as to improve the flexibility of the shielding unit and reduce the generation of eddy currents, and a dielectric filled in at least some of the gaps formed between some adjacent fragments among the fragments so as to reduce eddy current generation, thereby preventing an interruption by the conductor to the transmission/reception of the radiator and improving the properties of the radiator. Configured as such, the present invention blocks the effect of a magnetic field on components, such as a portable terminal device, or a user using same at the time of transmitting/receiving wireless power signals in a magnetic resonance mode, minimizes or prevents an interruption by the conductor, which may be adjacently disposed therearound, to the transmission/reception of the power signals, and can significantly improve the efficiency of wireless power transmission in a magnetic resonance mode by significantly improving the properties of the radiator. |
