Abstract: A drawn film of polyamide having an oxygen permeability coefficient of not more than 5 .times. 10.sup.-13 ml.cm/cm.sup.2.sec.cmHg, a breaking strength of not less than 14 kg/mm.sup.2, a breaking elongation of 30 to 150%, a yield strength of not less than 7 kg/mm.sup.2 and a yield elongation of 2 to 6%, which can be manufactured by drawing an undrawn polyamide film biaxially at a temperature within a certain range and optionally heat treating the resulting drawn film, the said undrawn polyamide film being made of a polyamide having a relative viscosity of about 2.0 to 4.0 when measured with a solution thereof in 96% sulfuric acid at a concentration of 1 g/100 ml at 25.degree. C and containing in the molecule not less than 70% (mol) of the repeating unit constituted with metaxylylenediamine or its mixture with paraxylylenediamine and an .alpha.,.omega.
