To obtain a printed-wiring board in which whether a copper paste protrudes between copper-foil lands at a narrow land interval or not can be detected easily.
The color of a surface in a narrow part in which the interval size between adjacent copper-foil lands 3a, 3b on a paper-, phenol- and copper- clad laminated board 4 is narrow so as hot to be capable of forming a resist layer 8 is set as a color which can be discriminated clearly from the color of a hardened copper paste 7. Specifically, the color of an adhesive layer 6 by which a copper foil is bonded to a paper-based material 5 at the paper-, phenol- and copper-clad laminated board 4 is set as a color which is complementary to the color of the hardened copper paste 7 or a white color.
