Further, in a case in which a magnetic field shielding sheet 130 is disposed on one surface of each of the antennas 121, 122, and 123, the accommodation groove 214 may be formed to have a predetermined depth to accommodate some or all of a thickness in which the thickness of each of the antennas 121, 122, and 123 and a thickness of the magnetic field shielding sheet 130 are combined. In addition, in a case in which a heat-radiation sheet (not shown) is stacked on one surface of the magnetic field shielding sheet 130, the accommodation groove 214 may be formed to have a predetermined depth to accommodate some or all of a thickness in which the thickness of each of the antennas 121, 122, and 123, the thickness of the magnetic field shielding sheet 130, and a thickness of the heat-radiation sheet are combined.

Meanwhile, as shown in FIGS. 8 and 9, a mesh body 314 may be disposed in a region corresponding to the antennas 121, 122, and 123 in the back cover for the portable terminal 310 according to another embodiment of the present invention to reduce the generation of the eddy current.

That is, the back cover for the portable terminal 310 according to the embodiment may include a through port 312 formed to pass therethrough in a predetermined area, and may have a shape in which the mesh body 314 is disposed in the through port 312. In this case, the through port 312 may be formed to pass through the back cover 310 to include areas corresponding to the antennas 121, 122, and 123.
