A novel aromatic diamino amide monomer of the structural formula (I), a novel aromatic polyamide of the structural formula (II) prepared by polycondensation of the monomer and an aromatic diacid halide, and an aromatic polyamide film produced from the polyamide which has high strength as well as high modulusity. <IMAGE> (I) wherein, each of two NH2 groups may be in meta or para-position to the amide bond. <IMAGE> (II) wherein, Ar represents a phenyl group, X represents CONH2 group in ortho-position to the amide bond, Y represents H, Cl, Br, I, NO2 or an alkyl or alkoxy group having 1 to 4 carbon atom, and n represents an integer between 10 and 100,000.
