Description of the Related Art A tip hood protruding forward from a tip body has an important function of securing the closest distance between an observation window and a subject in a forward-looking endoscope or the like. Generally, it is formed in a cylindrical shape corresponding to the columnar cross-sectional shape of the tip end body.

【発明が解決しようとする課題】内視鏡の観察視野形状
には、主に円形状と矩形状の二種類があるが、矩形状の
場合には対辺方向と対角方向とで視野角が大幅に相違
し、視野角が広い対角方向において観察視野が先端フー
ドで遮られないようにする必要がある。There are mainly two types of endoscope observation visual field shapes, a circular shape and a rectangular shape. In the case of a rectangular shape, the viewing angle in the opposite side direction and the diagonal direction is different. It is significantly different, and it is necessary to prevent the observation visual field from being obstructed by the tip hood in the diagonal direction where the viewing angle is wide.

ってしまうことになる。[0004] For this reason, the length of the distal end hood cannot be sufficiently ensured, and there are many cases where the observation window is too close to the subject during close-up observation and only indistinct observation can be performed. However, if the tip hood is extended, the diagonal direction of the rectangular observation field is blocked by the tip hood, and the field of view becomes narrow.
【０００５】そこで本発明は、矩形状の観察視野が先端
