Abstract:
There is provided an endoscope from which excellent close contact feeling is obtained and which is easy to grip in a case in which an operator is to grip a grip portion.
A grip portion of an endoscope has a cross-sectional shape symmetric with respect to a second center line. The grip portion includes a first curved surface, second curved surfaces, and ridges. The first curved surface is a curved surface that is convex outward from a plane, which includes an intersection point between the second center line and the first curved surface and the ridge, and a plane, which includes an intersection point between the second center line and the first curved surface and the ridge. The second curved surfaces are concave inward from planes parallel to the second center line.
