A flexible tube for an endoscope comprises a flexible elongated structural body and an outer cover provided over the elongated structural body. In this flexible tube, at least the outer peripheral part of the outer cover is made of a material which contains elastic resin and plant extract having an antibacterial property, and the plant extract is prepared using at least one plant selected from the group consisting of plants belonging to the order Ranunculales. Further, in the flexible tube, the plant extract and the resin that constitutes the outer cover are inert with respect to each other. According to the flexible tube described above, it is possible to provide a flexible tube for an endoscope that can not only exhibit excellent antibacterial property against bacteria and the like, but also sustain the antibacterial property over a long period of time.
