Endoscope having a bendable tube connected to a forward end member adapted to be inserted into a hollow body portion to be inspected and controlled from a control housing and an elongated flexible tube connecting the bendable tube and the control housing. The flexible tube has a thin tubular synthetic resin layer having a tubular net-like braid of non-metallic fibers embedded therein and another thin tubular synthetic resin layer having a tubular net-like braid of metallic fibers embedded therein, the superimposed resin layers coaxially covering the flexible core of the flexible tube, and the bendable tube comprises a tubular, knitted net-like braid of crimped synthetic fibers closely enveloping a bendable tubular core and a pliable resin tube closely enveloping the braid, thus providing adequate wall thickness for the flexible tube and the bendable tube while retaining sufficient flexibility and twist-resisting property.
