Beschreibung
Zusammenfassung:	A flexible tube for an endoscope includes a flexible elongated structural body and an outer cover provided over the elongated structural body. The outer cover is made of a material which contains polyurethane elastomer and polyester elastomer, in which compounding ratio of the polyurethane elastomer and the polyester elastomer in the material is 0.03-0.3 parts by weight of the polyester elastomer per 1 part by weight of the polyurethane elastomer. This flexible tube has excellent flexibility as well as various excellent properties such as chemical resistance, heat resistance and weather resistance.
