    摘要: Provided is a method of manufacturing a wiring board, in which; a composite adhesive sheet 20 is attached to one of the surfaces of a support substrate 10, and a double-sided CCL 30 is attached to the other surface. Then, in an integrated state of the above components, a multilayer wiring structure including a conductive layer and a resin insulating layer is formed on a metal layer 33 of the double-sided CCL 30 by a known build-up method. A thermally foamable adhesive layer 22 of the composite adhesive sheet 20 is then heated, thereby thermally decomposing a thermal foaming agent to generate gas, and the support substrate 10 is separated from the remaining bonded body. Thereafter, a carrier foil layer 32b and a copper foil layer 32a of a carrier-foil coated copper foil 32 are mechanically peeled from each other at a boundary between both the layers, thereby obtaining a wiring board 1.
