摘要

Disclosed is a dielectric layer-constituting material wherein unnecessary dielectric layers other than one in a capacitor circuit portion are removed by improving the positioning accuracy of a built-in capacitor circuit in a multilayer printed wiring board. Also disclosed is a capacitor circuit-forming member. Specifically disclosed is a process for producing a dielectric layer-constituting material including a step (a) wherein a first electrode circuit is formed by etching a conductive layer on one side of a metal-clad dielectric body which has conductive layers on both sides, and a step (b) wherein a dielectric layer-constituting material is formed by removing a dielectric layer exposed between the first electrode circuit. This method is characterized in that the step (b) is performed after the step (a). Also disclosed is a process for manufacturing a capacitor circuit-forming member wherein a second electrode is so formed as to face the first electrode using the thus-obtained dielectric layer-constituting material.
