PROBLEM TO BE SOLVED: To unerringly prevent inconveniences such as disconnection and unsoldering by absorbing a force applied to signal lines. SOLUTION: An endoscope incorporates a tip hard portion 14, a printed board 36 on which an image sensor 35 is mounted, and a plurality of signal lines 41 connected to the printed board 36 by soldering. The signal lines 41 are entwined around a comb-like elastic member 55. The elastic member 55 has a plurality of combteeth 56 to 61 and is stretchable in the insertion direction of an insertion portion. The signal lines 41 are entwined around the combteeth 56 to 61 in the form of a wave and have a sufficient length when stretched. When the part between the printed board 36 and a multicore cable 24 is stretched in accordance with the bending of a bending portion, an elastic member 55 never impose a load on the signal lines 41 because the combteeth 56 to 61 are spread. The signal lines 41 are maintained in a stable posture. COPYRIGHT: (C)2009,JPO&INPIT
