<p>An endoscope 2 includes: a window portion 15 that protrudes by a predetermined height from a flat portion 22; an air/water feeding nozzle 19 that is provided facing the window portion 15 from the flat portion 22, and that ejects a fluid toward the surface of the window portion 15; and an inclined portion 23 formed at a circumferential edge portion of the window portion 15; in which, in angles of inclination with respect to the flat portion 22 of the inclined portion 23, compared to the first angle of elevation ¸1 that is an angle in a direction along a first axis that passes through a center of the window portion 15 in an ejection direction of the fluid ejected from the air/water feeding nozzle 19, the second angle of elevation ¸2 that is an angle in a direction along a second axis that is orthogonal to the first axis at the center of the window portion is made a larger angle, thereby further improving cleanability and water draining property of the window portion 15.</p> |
