The resin sheet according to the present invention comprises a supporting body, and a layer that is provided on the surface of the supporting body and that contains a resin composition. The resin composition contains a cyanic acid ester compound and/or a phenolic compound, and an epoxy compound and/or a maleimide compound. At least one selected from the group consisting of the cyanic acid ester compound, the phenolic compound, the epoxy compound, and the maleimide compound, contains a compound having a biphenyl backbone. In the case where the resin composition contains an inorganic filler, the contained amount of the inorganic filler is 60 parts by mass or less with respect to 100 parts by mass of a resin solid content in the resin composition. The Vickers hardness (HV: 0.01) of a cured product of the resin composition is 10-19, and the thickness of the layer containing the resin composition is 2-20 μm. |
