Abstract: A method of manufacturing an endoscope includes: dividing some of signal lines into bundle portions; notching a part of a tube to form one or a plurality of notch portions; cutting at least one end portion of the tube in a state where the tube is folded with each notch portion to produce a first heat-shrinkable tube having cylindrical portions with aligned end portions in longitudinal directions of the cylindrical portions; inserting the divided bundle portions into the cylindrical portions of the first heat-shrinkable tube, respectively; inserting the signal lines into a second heat-shrinkable tube; heating at least an overlapping portion in a state where the first and second heat-shrinkable tubes partially overlap each other to cause heat shrinkage; inserting the signal cable and the channel into a tubular portion; and connecting the tubular portion to a distal end constituting portion to form the insertion portion.
