Zusammenfassung:	PROBLEM TO BE SOLVED: To attain effective utilization of a both-terminal end amino group blocked diorganopolysiloxane in the form of a mixture of an α-adduct and a β-adduct. SOLUTION: The manufacturing method for the polyamide silicone polymer is characterized in that (A) the both-terminal end amino-modified diorganopolysiloxane having groups represented by the formula: -B-NH2(B represents divalent hydrocarbon group) at both terminal ends of the molecule chain obtained by addition-reacting (a1) a diorganopolysiloxane having silicon atom-bonded hydrogen atoms at both terminal ends of the molecule chain and (a2) an active hydrogen non-protected amine represented by the formula: R1-NH2(R1represents a monovalent unsaturated hydrocarbon group), (B) an aromatic or aliphatic diamine, and (C) an aromatic or aliphatic dicarboxylic acid or its reactive derivative are reacted with each other.
