A wireless power transmission module operable in magnetic resonance method including a radiator unit for wireless power transmission, and a magnetic field shielding unit, disposed on a side of the radiator unit, for preventing disturbance of transmission and reception of the radiator due to the conductor and improving radiator characteristics, by providing a magnetic field shielding layer which includes shredded Fe-based alloy fragments and a dielectric filling at least a part of gaps between shredded Fe-based alloy fragments and some adjacent ones of the fragments to reduce eddy currents, to improve flexibility of and reduce eddy currents in the magnetic field shielding unit. When a wireless power signal is transmitted and received in a magnetic resonance method, the influence of a magnetic field on components of s a mobile terminal or a user can be blocked. Interference with the transmission/reception of the power signal due to the conductor can be minimized or prevented. The radiator characteristics and wireless power transmission efficiency can be remarkably improved.
