An endoscope having a rigid tube and a multi-layer flexible tube is disclosed, which mainly comprises an image-capture module, a first joint, a multi-layer flexible tube, at least one tensile rope, at least one electric wire, a second joint, and a rigid tube. One end of the image-capture module is utilized for capturing images. The first joint has one end connected to the other end of the image-capture module. The multi-layer flexible tube mainly comprises a helical steel ring layer, an inner woven net layer, a cladding layer and an outer spring layer. One end of the at least one tensile rope and one end of the at least one electric wire are connected to the first joint for fixation, respectively. The second joint has a first end formed with a convex thread that is screwed to the outer spring layer of the multi-layer flexible tube for fixation. The rigid tube has one end secured on the second end of the second joint. Accordingly, with an anti-torsion function of the multi-layer flexible tube, an efficacy of protecting at least one electric wire can be achieved.一種具有硬管及多層撓性管之內視鏡,主要包含有:一攝像模組、一第一接頭、一多層撓性管、至少一抗拉索、至少一電線、一第二接頭及一硬管組成。該攝像模組之一端用以擷取影像。該第一接頭之一端結合該攝像模組之另一端。該多層撓性管主要由一螺旋鋼圈層、一內編織網層、一披覆層及一外彈簧層組成。至少一抗拉索之一端及至少一電線之一端分別連接該第一接頭固定。該第二接頭之凸螺紋螺合該多層撓性管之外彈簧層固定。該硬管之一端固設於該第二接頭之另一端。藉此,該多層撓性管具有抗扭轉功能,以達保護該至少一電線之功效。100‧‧‧具有硬管及多層撓性管之內視鏡11‧‧‧攝像模組12‧‧‧第一接頭121‧‧‧第一結合槽122‧‧‧第一凸柱124‧‧‧第一抗拉索孔126‧‧‧第一電線孔14‧‧‧多層撓性管144‧‧‧披覆層146‧‧‧外彈簧層16‧‧‧抗拉索17‧‧‧電線18‧‧‧第二接頭181‧‧‧第二結合槽182‧‧‧凸螺紋184‧‧‧第二凸柱186‧‧‧第二抗拉索孔188‧‧‧第二電線孔19‧‧‧硬管
