A rotor of a treatment apparatus includes a first outer surface spaced apart from the longitudinal directions axis of a flexible tube section by a first distance in radial directions, and a second outer surface spaced apart from the longitudinal directions axis of the flexible tube section by a second distance smaller than the first distance in the radial directions. The treatment apparatus includes a first rotating operation wire extending from a wire fixing portion to the first outer surface, a second rotating operation wire extending from the wire fixing portion to the second outer surface, and a wire intersecting portion in which the first and second rotating operation wires intersect at positions apart from each other in a state that the second rotating operation wire is located on an inner direction side of the first rotating operation wire.
