1. a wireless communication terminal (100) provides with shield member and shields to prevent the electronic device of electromagnetic interference, is positioned at housing case, is characterised in that to comprise:

  • Integrated circuit (132);

    Be connected with this integrated circuit to carry out first resonant circuit (110) of contactless communication with external devices;

    AndWith second resonant circuit (120) of this first resonance,And the loop coil of this first resonant circuit is positioned in the side of shield member of the insertion screening electron device of this wireless communication terminal,The loop coil of this second resonant circuit is positioned on the opposite side that inserts this shield member,The loop coil of this second resonant circuit is arranged to and makes by the formed loop of this second resonant circuit zone greater than the zone that is combined in the shield member in this wireless communication terminal,This second resonant circuit is not electrically connected with this first resonant circuit,This housing is to constitute by passing through hinge (151) first module connected to one another (161) and Unit second (162),This housing is configured to and can folds this first module and this Unit second as basic point by enough this hinges, and perhaps this housing is configured to make this first module freely to rotate with respect to this Unit second,This Unit second comprises this first resonant circuit, this second resonant circuit and this shield member, andThe loop coil of this second resonant circuit has the loop coil that switch (123) comes to open and close with the motion association ground of hinge this second resonant circuit.
