PURPOSE: A method for shielding an electromagnetic wave in a wireless communication apparatus is provided to mount a portion of a conductor on one side of a case where the electromagnetic wave is generated in large quantity, and to shield the electromagnetic wave, thereby preventing deterioration of transceiving features of an antenna. CONSTITUTION: An output signal line of a transmitting power amplifier and a local signal line inputted to a mixer end are shielded through a conductor(20), without shielding an entire case(10). Most electromagnetic waves are generated in the output signal line of the transmitting power amplifier. The conductor(20) is attached to an inner side of the case(10) by using an adhesive or a method of fusing supersonic waves while molding the case(10). The width of the conductor(20) is bigger than width of a signal line(14) by 1 to 1.5 times.
