Disclosed herein is an electromagnetic wave shield box for shielding a wireless terminal received therein from external electromagnetic waves. The electromagnetic wave shield box includes a box body for allowing the wireless terminal to be received therein, the box body having a coupling antenna mounted therein, the coupling antenna being spatially coupled with an antenna of the wireless terminal, a cover constructed to be openable and closable with respect to the box body, a reference table mounted at a predetermined position above the coupling antenna in the box body, the reference table having a reference surface, which is referenced when the wireless terminal is disposed thereon, a loading unit for allowing the wireless terminal to be loaded thereon, the loading unit being movable along the reference surface, and fixing means for detachably fixing the loading unit, on which the wireless terminal is loaded, to a predetermined position of the reference surface of the reference table to define the positional relation between the antenna of the wireless terminal and the coupling antenna.
