A resin composition which is well balanced among moldability, heat-resistance and mechanical strength and comprises an aromatic polyamideimide resin (A) and a polyester resin (B), a polyphenylene sulfide resin (C) or a resin (D) capable of forming an anisotropic molten phase. The resin component (A) is composed of 5-95 mol % of repeating units represented by general formula (1) and 95-5 mol % of at least either repeating units represented by general formula (2) or ones represented by general formula (3), and is produced by the process which comprises polymerizing an aromatic tricarboxylic acid anhydride, at least either aromatic or aliphatic dicarboxylic acid, and an isocyanate compound in two or more steps, wherein the reaction in the first step is conducted in the temperature range of 50-110 °C and those in the second and subsequent steps are conducted in the temperature range of over 110 °C to 200 °C. In said formulae Ar represents a trivalent aromatic group, Ar₁ represents a divalent aromatic group, R₁ represents a divalent aliphatic group, and R represents a divalent aromatic or aliphatic group.
