Endoscope

An endoscope comprising:

• an insertion part to be inserted into a subject;
• a distal end surface provided at a distal end of the insertion part;
• an observation window provided on the distal end surface to observe an interior of the subject;
• a nozzle provided on the distal end surface to jet a fluid toward the observation window;
• and
• a plurality of protective projections disposed at an outer peripheral part of the distal end surface and provided to project forward of the observation window,
• wherein the plurality of protective projections have a same height as the nozzle or are projected forward of the nozzle,
• wherein the observation window and at least a portion of the nozzle are included within an outer ring region surrounded by the plurality of protective projections, in plan view of the distal end surface,
• wherein the distal end surface has a first surface on which the nozzle is disposed and a second surface which is provided at a projecting part projecting forward from the first surface and on which the observation window is disposed,
• wherein the plurality of protective projections include a first protective projection, a second protective projection, and a third protective projection, and the second and third protective projections are provided on the first surface,
• wherein the nozzle is disposed between the second protective projection and the third protective projection,
• wherein the distal end surface has a fluid discharge surface that is provided on a side opposite to the nozzle with respect to the observation window and is inclined rearward as a distance from the observation window increases,
• wherein the first protective projection is provided at a position adjacent to the fluid discharge surface, and
• wherein the first protective projection is provided on the second surface, and is disposed at a position offset to one side of an imaginary straight line connecting a center of the nozzle and a center of the observation window.
