<p><P>PROBLEM TO BE SOLVED: To provide an endoscope in which a degree of freedom of the design of a helical angle or the like is high and the operability of an insertion part can be improved at a low cost in the one in which a helical shape part is arranged on the outer periphery of a flexible, thin and long tube insertable to a subject; and also to provide an endoscopic system. <P>SOLUTION: The endoscope is provided with an insertion part body. The insertion part body comprises: a flexible inner layer tube 49a which can be inserted to the subject; and the helical shape part 51 as a driving force generating part formed of a sparsely wound metallic coil 91 and a resin thin film 92 connecting the coils and arranged on the outer periphery of the inner layer tube 49a so as to be freely rotated with the inner layer tube 49a as an axial center. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
