PROBLEM TO BE SOLVED: To provide an endoscope excellent in operability and capable of making a treatment ingredient move within a necessary range in the visual field of an observation port, without deteriorating the insertion/extraction of the treatment ingredient and also without damaging the ingredient. SOLUTION: When raising a treatment ingredient inductor 31, its rising angle is set by abutting the slant face 37 for stopper of the inductor 31 on the bottom face 38 of an inducing port 15 Specifically, the rising angle is set to a position at which the rising and setting direction of the ingredient 16 guided by the inductor 31 coincides roughly with the central line direction of visual field in the observation port 10.
