PROBLEM TO BE SOLVED: To obtain the subject composition efficiently cross-linkable and excellent in heat resistance, mechanical properties, etc., by adding a specific radical former and a polyfunctional monomer to a polyamide-based resin. SOLUTION: This composition comprises (A) a polyamide-based resin (e.g. a polyamide obtained by a condensation polymerization of an aliphatic, an alicyclic or an aromatic diamine such as hexamethylenediamine with an aliphatic, an alicyclic or an aromatic dicarboxylic acid such as adipic acid), (B) a radical former selected from a 1,2-diphenylethane derivative represented by formula I (R1 to R4 are each H, a halogen or the like; X and Y are each H, a halogen or the like) (e.g. 2,3-dimethyl-2,3-diphenylbutane) or a diisopropylbenzene oligomer represented by formula II (n is 2-50) and (C) a polyfunctional monomer having >=2 carbon-carbon double bonds in the molecule (e.g. triallyl isocyanurate). The amounts of the respective components used based on 100 pts.wt. of the component A are preferably 0.01-10 pts.wt. of the components B and C.
