Provided are a flex-rigid wiring board having an increased shielding effect and improved productivity with reduced number of manufacturing process steps, and a method for manufacturing the flex-rigid wiring board. The flex-rigid wiring board consists of a flexible cable section (32) having a shielding layer (45) on an outer surface, and a rigid mounting section (34) having a wiring layer (47) provided on the same surface as the shielding layer (45). The shielding layer (45) and the wiring layer (47) are made of a same sheet of continuous copper foil (46). The wiring layer (47) is plated and is made thicker than the shielding layer (45). A same continuous insulating layer (48) is provided on outer sides of the shielding layer (45) and the wiring layer (47) of the mounting section (34).
