Claim Text:
1. A method for manufacturing a flex-rigid wiring board, comprising: positioning a flexible board and a non-flexible substrate adjacent to each other; forming a metal layer over the flexible board such that the metal layer is configured to stop laser irradiation from reaching into the flexible board; forming an insulating layer such that the insulating layer covers the metal layer, the flexible board and the non-flexible substrate; irradiating laser upon the insulating layer such that the metal layer and a portion of the insulating layer covering the metal layer are cut; and removing the metal layer and the portion of the insulating layer covering the metal layer from the flexible board such that at least a portion of the flexible board is exposed, wherein the flexible board and the non-flexible substrate are separate structures in the positioning, and the flexible board has a flexible substrate and a conductor pattern formed over the flexible substrate.
