PROBLEM TO BE SOLVED: To provide a flexible tube of an endoscope improving insertion/extraction properties by supplementing a low-repulsive part with a repulsive property, and to provide an endoscope including the flexible tube.SOLUTION: A spiral tube 50 includes a closely wound part 51 to which initial tension is applied and loosely wound parts 53a and 53b concatenated to at least one end of the closely wound part 51. An inclusion object 80 is covered by a concatenation part 55 in which the closely wound part 51 and the loosely wound parts 53a and 53b are mutually concatenated, and has a first supplement area 95a to which the initial tension is applied to supplement the spiral tube 50 with the repulsive property.COPYRIGHT: (C)2014,JPO&INPIT【課題】弾発性が低い部分に弾発性を補充し、挿抜性が向上する内視鏡の可撓管部と、この可撓管部を有する内視鏡とを提供すること。【解決手段】螺旋管50は、初張力が付与されている密着巻き部51と、密着巻き部51の少なくとも一端に連接されている疎巻き部53a,53bとを有している。内蔵物80は、密着巻き部51と疎巻き部53a,53bとが互いに連接する連接部分55によって覆われ、螺旋管55の弾発性を螺旋管に補充するような初張力が付与されている第1の補充領域95aを有する。【選択図】 図2A
