摘要

Provided is an endoscope tube which has flexibility that allows the endoscope tube to endure being used in a soft endoscope even when the diameter thereof is increased, and in which damage to a fluorine resin layer forming the inner circumferential surface of the endoscope tube is easily detected. This endoscope tube 100 is provided with: an airtight inner layer tube member 101 comprising a fluorine resin layer; an air permeable outer layer member 102 which has a lower hardness than the inner layer tube member 101 and covers the outer circumferential surface of the inner layer tube member 101; and a coil-like reinforcing member 103 wound in a helical groove section 104 formed in the outer circumstance surface of the outer layer member 102. An endoscope 2 comprises a treatment insertion channel 23 which is formed by the endoscope tube 100 and provided in an insertion part 10.
