May 1, 2013
Disclosed are a shielding apparatus and a wireless power transmission apparatus. The shielding apparatus included in a wireless power transmission apparatus for transmitting power to a wireless power reception apparatus in wireless includes a first shielding unit changing a transmission path of a portion of a magnetic field generated from a transmission coil of the wireless power transmission apparatus, and a second shielding unit shielding the portion of the magnetic field which has passed through the first shielding unit. The second shielding unit is placed on the first shielding unit. A real component value of permeability of the first shielding unit is greater than an imaginary component value of the permeability of the first shielding unit, and an imaginary component value of permeability of the second shielding unit is greater than a real component value of the permeability of the second shielding unit.
