PROBLEM TO BE SOLVED: To provide a gel formation inhibitor capable of inhibiting frequent formation of the gel, when a polyamide-based resin composition consisting mainly of m-xylene adipamide is melted and kneaded, and capable of producing a polyamide-based biaxially oriented film having an excellent appearance with high productivity, and to provide a polyamide-based biaxially oriented film using the inhibitor. SOLUTION: This gel formation inhibitor comprises at least one kind selected from an aliphatic amide, an aliphatic bisamide, and a metallic soap. The polyamide-based biaxially oriented film has at least one layer formed out of a resin composition given by adding 0.01-0.20 pt.wt. of the gel formation inhibitor to 100 pts.wt. of a polyamide-based resin which comprises 100-60 pts.wt. of a polyamide composed of structural units formed by polycondensation reaction of m-xylylenediamine and adipic acid and 0-40 pts.wt. of an aliphatic polyamide.
