Zusammenfassung:PURPOSE:To provide a method for manufacturing an effective and economical tape carrier for TAB. CONSTITUTION:In a method of manufacturing a tape carrier for TAB in which a plurality of conductive leads having desired patterns are formed on an insulating film 1 and a plated layer is arranged on the surface of the leads, desired patterns have beforhand been formed so that respective conductive leads and adjoining patterns are electrically indepent of each other. Thereafter, all the leads and the adjoining patterns are electrically connected to each other by forming a conductive membrane 10, and continuously after all the leads are electroplated through the conductive membrane 10, the conductive membrane 10 is removed to make the leads electrically independent of each other.
