<p>Provided is a flex-rigid wiring board wherein a resin weak to chemicals is surely protected without increasing man-hour during a manufacturing step. A method for manufacturing such flex-rigid wiring board is also provided. The flex-rigid wiring board is composed of a flexible section (A) having a base film (24), i.e., an insulating layer, and a copper foil (26), i.e., a conductor layer; and a rigid section (B), which is integrally arranged with the flexible section (A) and has circuit patterns (28, 29). One surface of the base film (24) of the flexible section (A) is entirely covered with the copper foil (26). The copper foil (26) is removed when etching is performed in an intermediate processing step. At the boundary between the flexible section (A) and the rigid section (B), a part extending from the removed copper foil (26) is embedded in the rigid section (B).</p> |
