Abstract: PURPOSE: To provide a polytriazine dielectric composite material, which has a low dielectric constant and is superior in procesability, and a microelectronic circuit package with this composite material incorporated therein. CONSTITUTION: A thermoplastic resin filler is made to disperse in a polytriazine dielectric composite material and, while the dielectric constant of the composite material is held low, the brittleness of a triazine polymer is decreased and the ductility of the polymer is increased. This triazine polymer is used as a substrate to obtain a multilayered printed circuit card.
