摘要:
There is provided an endoscope and an endoscope flexible section that can secure bending rigidity and have the resistance against high temperature-and-pressure steam during sterilization. The endoscope flexible section includes a spiral tube, a net-like tube, and an outer cover member. The spiral tube is formed by winding a belt-like member made of metal, in a spiral shape. The net-like tube is formed in an annular shape on the periphery of the spiral tube by braiding thin metal wires. The outer cover member is formed on the periphery of the net-like tube. In the outer cover member, a polyparaxylene resin layer is formed in a pattern on the periphery of a cover layer that covers the periphery of the net-like tube and is made of fluororubber. The polyparaxylene resin layer is a pattern of the plural rings that are disposed in a circumferential direction at predetermined intervals.
