2. Description of the Related Art A plurality of prepregs in which a glass substrate is impregnated with a resin varnish are laminated, and a pressure-bearing body having a metal foil disposed on the surface thereof is heated and pressed to obtain a metal-clad laminate. Also,
A prepreg is placed on the inner layer wiring board, and a pressure-bearing body having a metal foil disposed on the surface thereof is heated and pressed to obtain a multilayer metal-clad laminate. Printed wiring boards in which circuits are formed by subjecting these metal-clad laminates to etching or the like are used mounted on various electric devices. Above all, metal-clad laminates used for printed wiring boards for communication devices such as mobile phones,
Depending on the area of the circuit to be designed, there is a demand for a subdivided material having a dielectric constant in a predetermined range. In order to obtain the dielectric constant of the metal-clad laminate within a predetermined range, there is a method of adjusting the amount of resin of the prepreg to be used.However, with the amount of resin of the prepreg, if the amount of resin is too small, the adhesive strength is reduced. There is a limit only in the range of the resin amount. In addition, multiple types of prepregs are made with different resin varnishes,
There is also a method of obtaining a finely divided dielectric constant by combining these, but if the type of the resin varnish is different, the adhesion between the cured insulating layers of the prepreg is weak, and delamination tends to occur in the metal-clad laminate.

According to the method for manufacturing a metal-clad laminate according to the second aspect of the present invention, the prepreg B constituting the laminate uses a resin varnish containing titanium oxide, and the titanium oxide directly contributes to the curing of the resin. When the prepreg A and the prepreg B are hardened, the prepreg A and the prepreg B are hardened with each other because the same resin is used. Therefore, delamination does not occur in the metal-clad laminate. Further, since a laminate is formed using prepregs having different dielectric constants, a metal-clad laminate having a desired dielectric constant can be obtained by adjusting the ratio of prepreg A and prepreg B constituting the laminate.
