(57) [Summary] [Purpose] A laminated board with a high dielectric constant and low dielectric loss tangent, with good machinability, workability, and dimensional stability. [Structure] An inorganic powder having a dielectric constant of 10 or more with respect to 100 parts by weight of a thermosetting resin containing (a) an epoxy resin, (b) a phenol-added conjugated diene polymer, and (c) a curing accelerator. Is added to 80 to 250 parts by weight, and a glass cloth or a glass nonwoven cloth is impregnated and dried, and a prepreg obtained by laminating and molding is laminated. |
