The present invention provides a copper-clad laminate characterized in that an electrolytic copper foil on the glossy surface side of which a copper electrodeposit is formed, is bonded at its glossy surface side to one side or each of both sides of a substrate, which has a fine-pitch wiring (circuit) pattern and exhibits a high etching factor. The present invention further provides a copper-clad laminate which can be suitably employed in the production of such a printed wiring board.
