PROBLEM TO BE SOLVED: To improve flexibility of an endoscope shaft having a working conduit and a number of supply and/or functional conduits. SOLUTION: Supply and/or functional conduits 3 of the endoscope shaft 1 are arranged in spirals, in serpentine and/or zigzag shape around or along the working conduit 2 which is a flexible hose or a pipe preferably made of a plastic material. Around the working conduit 2, a jacket 4 made of a synthetic resin foam is formed. Thereby, flexibility or bendability of the endoscope shaft is achieved. COPYRIGHT: (C)2005,JPO&NCIPI
