This means that in metal-clad laminates and wiring boards obtained using prepregs with glass cloth, a difference in relative permittivity occurs between the portion where the yarns constituting the glass cloth are present and the portion where the yarns are not present. Possibly.

- a resin composition according to one embodiment of the present invention is a polyfunctional vinyl aromatic copolymer containing repeating units (a) derived from a divinyl aromatic compound and repeating units (b) derived from a monovinyl aromatic compound ( A), a curing agent (B), at least one high dielectric constant filler (C) selected from the group consisting of a titanate compound filler (C1) and a magnesium oxide filler (C2), and a silica filler (D). and wherein the content ratio of the high dielectric constant filler (C) and the silica filler (D) is 10:90 to 90:10 in mass ratio.
- the polyfunctional vinyl aromatic copolymer (A) contained in the resin composition By curing the polyfunctional vinyl aromatic copolymer (A) contained in the resin composition together with the curing agent (B), the polyfunctional vinyl aromatic copolymer (A) is preferably cured. It is considered that a cured product having excellent heat resistance can be obtained. Moreover, since the resin composition contains the polyfunctional vinyl aromatic copolymer (A), it is believed that a cured product having a low dielectric loss tangent can be obtained by curing. This cured product is considered to have not only a low dielectric loss tangent but also a low dielectric constant. By including the high dielectric constant filler (C) in the resin composition, the dielectric constant of the cured product is increased. It is considered possible.
- the resin composition contains not only the high dielectric constant filler (C) but also the silica filler (D), and by adjusting the content ratio thereof to the above ratio, the dielectric loss tangent of the cured product is increased.

In this case, for example, the amount of the resin composition to be blended will differ depending on the thickness of the prepreg, etc., and the relative permittivity of the obtained cured prepreg will differ.
- the resin composition according to the present embodiment has a high relative dielectric constant as described above, the difference from the relative dielectric constant of the fibrous base material can be reduced.
- the difference in the dielectric constant of the cured product of each prepreg due to the difference in the blending amount of the resin composition in the prepreg becomes small. Therefore, even if there is a difference in the thickness of the insulating layer provided on the wiring board, the difference in the dielectric constant is small.
- the cured product of the resin composition has a high dielectric constant as described above, the difference between this dielectric constant and the dielectric constant of the fibrous base material provided in the prepreg becomes small. Also, the occurrence of skew in the finally obtained wiring board can be suppressed.
- the insulating layer is required to have a low coefficient of thermal expansion. Therefore, a substrate material for forming an insulating layer of a wiring board is required to obtain a cured product with a low coefficient of thermal expansion. For this reason, substrate materials such as wiring boards are required to have a high dielectric constant, a low dielectric loss tangent, excellent heat resistance, and a low coefficient of thermal expansion, as described above.
