PURPOSE: A highly rigid electromagnetic interference shielding composite is provided to excellent dimensional stability by replacing an existing metal material. CONSTITUTION: A thermoplastic resins (40) of a highly rigid electromagnetic interference shielding composite forms a continuous phase. A semi-dispersed phase is formed by a first metal filler (10), a second metal filler (20) and a surface-treated carbon fiber (30). The first filler continuously or discontinuously surrounds the surface of the second metal filler. The surface-treated carbon fiber is treated by resin and metal and the treated resin consists of polyamide and epoxy resin. The melting point of the thermoplastic resin, the first metal filler and the second metal filler satisfies Tma-30°C> Tmb and Tma+500°C < Tmc, respectively. |
