<P>PROBLEM TO BE SOLVED: To provide a simple manufacturing method which improves reliability of a side electrode of a flexible wiring board having an insulator layer formed of a liquid crystal polymer. <P>SOLUTION: A method for manufacturing a flexible wiring board comprises the steps of: forming a double-sided wiring raw board in which a first conductive metal layer and a second conductive metal layer are electrically connected by a conductive bump penetrating the insulator layer; forming a through-groove which penetrates the double-sided wiring raw board in a thickness direction, so as to expose at least a part of the conductive bump; and forming the side electrode on at least the conductive bump exposed on an inner wall surface of the through-groove, by plating. <P>COPYRIGHT: (C)2012,JPO&INPIT |
