An antenna feed line for a portable terminal is provided that includes first films in which shielding lines are formed lengthwise and a second film disposed between the first films and having at least one pair of signal lines formed lengthwise. The antenna feed line is a flexible printed circuit having a layered structure of the first films and the second film, while the signal lines are shielded by the shielding lines. Use of the antenna feed line allows a stable connection to be maintained in spite of external shock, and signal loss during transmission/reception can be reduced. Moreover, the antenna feed line can be easily fixed inside the portable terminal.
