<p>The present invention relates to a method for manufacturing an intenna by creating a recess on a case of a portable device by irradiating a laser beam and coating the recess with an electrically conductive metallic material. The method comprises: a coating step, a recess formation step, a plating step, and a cleaning step. The coating step forms a metal seed layer by coating the entire surface of the case with a metal seed. The recess formation step creates an intenna recess by irradiating a laser beam onto the case where the metal seed layer is formed, by which the metal seed of the metal seed layer adheres to an inner surface of the intenna recess. The plating step plates the inner surface of the recess with an electrically conductive metal material. The cleaning step cleans the case in order to remove the metal seed layer remaining in areas outside the intenna recess.</p> |
