Abstract
The flexible endoscopehas a flexible insertion portionto be inserted in an observation zoneof a MRI apparatus. The insertion portionhas an inner tubemade of resin, triple helical tubescovering the inner tubeand an outer tubemade of resin and covering the triple helical tubes. The triple helical tubesinclude a first helical bandhelically wound around an outer peripheral surface of the inner tube, a second helical bandhelically wound around an outer periphery of the first helical bandin a direction opposite to a winding direction of the first helical bandand a third helical bandhelically wound around an outer periphery of the second helical bandin a direction opposite to the winding direction of the second helical band. The first to third helical bandsare made of phosphor bronze or copper-silver alloy, which are materials having low magnetic susceptibility.
