A polyamide resin composition comprising: (A) 100 parts by weight of at least one member selected from a polyamide-11 resin and a polyamide-12 resin; optionally (B) from 3 to 30 parts by weight of a modified polyolefin resin; and (C) from 3 to 25 parts by weight of a plasticizer mixture comprising a plasticizer (C1) and a plasticizer (C2). The modified polyolefin resin (B) is either a modified polyolefin (B1) which is a copolymer of an olefin comprising at least one of ethylene and propylene, with an .alpha.,.beta.-unsaturated carboxylic acid or a derivative thereof, or a modified polyolefin (B2) which is a graft polymer obtained by grafting an .alpha.,.beta.-unsaturated carboxylic acid or a derivative thereof onto a copolymer of an olefin comprising at least one of ethylene and propylene. The plasticizer (C1) has a solidifying point of -40.degree. C. or lower and is at least one member selected from the group consisting of phthalic esters, fatty acid esters, polyhydric alcohol esters, phosphoric esters, trimellitic esters, and epoxy plasticizers, and the plasticizer (C2) is at least one member selected from the group consisting of benzenesulfonic acid alkylamides, toluenesulfonic acid alkylamides, and alkyl hydroxybenzoates.
