Abstract
The flexible tube includes a plurality of spiral tubes fitted with each other, and each spiral tube is formed by winding a band-like element and includes a densely wound portion and a loosely wound portion. The loosely wound portion of a first spiral tube is covered with the densely wound portion of a second spiral tube, so that the flexible tube has uniform hardness and resiliency. The flexible tube is suitably applied to an insertion device.
