The present invention provides a coated base fabric for airbags including: a cloth obtained by weaving polyamide (PA) fiber yarns; and a PA elastomer coating film formed on one surface or both surfaces of the cloth, wherein the coated base fabric has predetermined air tightness and flexibility, is easily converted to a PA reproduced material, and is obtained by fusing a coating film (16) made of an airflow suppression PA elastomer on one surface or both surfaces of a cloth (14) obtained by weaving yarns (12) and (12A) made of a polyamide (PA) fiber, as the PA elastomer, soft PA is normally used, which has a melting point (ASTM D3418) of 135 to 200°C, a difference between the melting points of the PA fiber and PA elastomer being 80 to 120°C.
