Abstract: An endoscope system is provided with: a sheath; an endoscope; a field-of-view ensuring part that has an expansion member formed of a sheet curved about the longitudinal axis of the sheath and a drive member generating an expansion force for expanding the expansion member in the radial direction and that is configured to project from and retract into the distal end of the sheath. The expansion member has a slit extending from the distal end toward the base end and is deformed from an expanded form in which expansion member has a larger outer diameter than the outer diameter of the sheath into a contracted form in which expansion member has a smaller outer diameter than the inner diameter of the sheath, by being rolled about the longitudinal axis.
