Abstract:
Provided is an endoscope tube that has flexibility to withstand use in a flexible endoscope even in a case where the diameter is increased and easily detects damage to a fluororesin layer that forms an inner peripheral surface. The endoscope tube 100 includes an airtight inner layer tube member 101 that is made of a fluororesin, a permeable outer layer member 102 that has a hardness lower than that of the inner layer tube member 101 and covers an outer peripheral surface of the inner layer tube member 101, and a coil-shaped reinforcing member 103 that is wound around a spiral groove part 104 formed on an outer peripheral surface of the outer layer member 102. The endoscope 2 includes a treatment tool insertion channel 23 formed by the endoscope tube 100 in an insertion part 10.
