摘要:
A composite dielectric is formed with a matrix synthetic resin and particulate porous, inorganic dielectric dispersed in the matrix synthetic resin. The dielectric constant of this composite dielectric can be thereby elevated effectively without enlarging the dissipation factor (tan .delta.) of the composite dielectric.
