PURPOSE:A material having extremely improved transparency, X-ray and neutron ray shielding ability while keeping improved mechanical strength of resin of its own, obtained by blending a polyamide resin with a compound containing an element of group IV of the periodic table. CONSTITUTION:100pts.wt. polyamide resin is blended with 5-100pts.wt. compound containing an element of group IV of the periodic table. A polyamide having >=10,000 number-average molecular weight is used as the polyamide. A zinc halide or a tin halide is preferable as the compound.
