Abstract: An endoscope manipulation training apparatus includes: a body including an organ support plate, two support leg plates, and an insertion tube support body; and a net body. Fitting portions are formed on both end portions of the organ support plate, threaded holes are formed in both corner portions of both end surfaces of the organ support plate, a fitting hole is formed in one of the fitting portions such that the fitting hole extends inward from an end surface of the fitting portion, and a latch groove is formed in the one of the fitting portions on both sides of the fitting hole. The support leg plate is formed such that an inner peripheral surface and an outer peripheral surface exhibit a regular octagonal shape.
