PROBLEM TO BE SOLVED: To provide a polyamide resin composition which has the yellowness increase inhibited even it has suffered a long time- or repeated heat hysteresis and which has the excellent mechanical properties such as toughness and the like and to provide a manufacturing method thereof. SOLUTION: The method for manufacturing a polyamide resin composition, comprising blending a metal compound aqueous solution consisting of a metal compound expressed by general formula: A<SB>X</SB>B<SB>Y</SB>O<SB>2</SB>(wherein, A is a metal element of Periodic Table Group 1, or is one selected from Cu, Ag and Pt; B is one selected from Al, Fe, Te, Ti, Sc, In, Y, Ni, Co, Cr, Mn, Ga, and Rh; and 0<X<4 and 0<Y<2) and of an acid component with at least one of a polyamide raw material and a polyamide molten material, is characterized in that the above metal compound aqueous solution has a concentration of the metal compound of 0.01-10% by weight and has a content of the acid component of 10-10,000 parts by weight relative to 100 parts by weight of the metal compound.
