<p>It is an object of the present invention to provide a capacitor layer forming material which is applicable to printed wiring boards manufactured through a high-temperature processing of 300°C to 400°C of a fluorine-contained resin substrate, a liquid crystal polymer and the like, and exhibits no deterioration of the strength after a high-temperature heating. In order to achieve the object, a capacitor layer forming material for a printed wiring board which comprises a first conductive layer used for forming a top electrode, a second conductive layer used for forming a bottom electrode and a dielectric layer between the first and second conductive layers, characterized in that for the second conductive layer, a nickel layer or a nickel alloy layer is employed. The nickel layer or the nickel alloy layer as the second conductive layer preferably has a thickness of 10 micron meter to 100 micron meter. Further, the sol-gel method is suitably employed to form the dielectric layer on the nickel layer or the nickel alloy layer constituting the second conductive layer.</p> |
