PROBLEM TO BE SOLVED: To provide a master batch which is based on a fluoropolymer used as a processing aid in the extrusion of a polyolefin (D), especially in a film extrusion molding of a polyolefin, and to provide a manufacturing method thereof. SOLUTION: The master batch comprises 1-50% by weight of a blend consisting of at least one kind of a fluoropolymer (A) and of at least one kind of a surfactant (B) and 99-50% by weight of a polyolefin (C), and is obtained by mixing homogeneously these two components (A) and (B) at the temperature where the greater part of at least one component or the surface thereof becomes a molten state, and thereafter by mixing the polyolefin (C) thereto.
