The present invention relates to an electric mat having a unit for shielding an electromagnetic wave. The electric mat includes a bottom part which forms the bottom surface of an electric mat; a heating line which is arranged on the bottom part, covers an electric wire transferring heat with an insulating coating, and generates heat by applying an external power; a metal shielding part which is arranged on the heating line and shields an electromagnetic wave emitted through the heating line; a cover part which is arranged on the metal shielding part and functions as the outer cover of the electric mat; and a connector which is connected to the heating line and receives a control signal according to the power and temperature control from a mat controller. The heating line consists of two twisted lines. An electromagnetic wave emitted from one heating line is attenuated by the other heating line. Thereby, the radiation of an electromagnetic wave emitted from the electric mat to the outside can be fundamentally shielded by a simple method. |
