    Abstract: PROBLEM TO BE SOLVED: To provide a copper-clad laminate preferable as an all-polyimide substrate material, which solves problems of low bonding strength and low transparency of a remaining polyimide film after etching-removal of a copper foil, the problems having been impossible to solve in a conventionally well-known copper-clad laminate for a substrate. SOLUTION: The copper-clad laminate includes a low roughness copper foil and a polyimide film laminated thereon, in which the film, after etching the copper foil, has light transmittance of 40% or higher at a wavelength of 600 nm and a haze of 30% or lower, and bonding strength therebetween is 500 N/m or higher. An alternative copper-clad laminate includes a copper layer and a polyimide film laminated thereon, in which the film, after etching the copper layer, has light transmittance of 40% or higher at a wavelength of 600 nm and a haze of 30% or lower, bonding strength therebetween is 500 N/m or higher and the bonding strength after heat-treatment for 1,000 hours at 150°C is 285 N/m or higher.

    Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board capable of correctly (highly precisely and unfailingly) forming a conductor pattern including a very fine wiring pattern etc.; and to provide a method for manufacturing the printed wiring board. SOLUTION: The conductor pattern 4 made by laminating a base metal pattern 2 and a plating metal pattern 3 is formed by the method including a step of forming a base metal pattern 2; a step of coating a negative photoresist 6 on one surface where the base metal pattern 2 is formed; a step of irradiating the photoresist 6 with a light 7 transmitting an insulative substrate 1 by using the base metal pattern 2 to expose the photoresist 6, thereby forming a plating resist pattern 8; and a step of plating, using the base metal pattern 2 as a seed layer, only on a portion where the plating resist pattern 8 is not formed by using the plating resist pattern 8, thereby selectively forming a plating metal pattern 3 on only the base metal pattern 2.
