PROBLEM TO BE SOLVED: To provide a plasticized polyamide resin composition having high thermal processing stability, and a tube using the composition that has a high long-term reliability. SOLUTION: This polyamide resin composition comprises (A) 70-97 wt.% of a polyamide resin and (B) 3-30 wt.% of a plasticizer comprising an ester of p- and/or o-hydroxybenzoic acid and an aliphatic alcohol having a branched chain, wherein the rate of the content of a phenolate dimer (B-a) to the content of an unreacted alcohol (B-b) in the plasticizer (B) is 0.3<(B-a)<(B-b)<3, and the content of the unreacted alcohol (B-b) is≤4 wt.%.
