Endoscope

An endoscope, comprising:

• a first flat surface formed at a distal end portion of an insertion part to be inserted into a subject, and orthogonal to an axial direction of the insertion part;
• an observation window provided at the distal end portion for allowing image light of the subject to be taken therethrough, with a surface of the observation window as a light incidence plane;
• a forceps outlet disposed on the first flat surface;
• a first illumination window provided at the distal end portion to irradiate a subject with illumination light;
• a second illumination window provided at the distal end portion to irradiate the subject with illumination light;
• a fluid jetting nozzle arranged at the first flat surface to jet a fluid toward the observation window and fixed at the distal end portion of the insertion part;
• and
• an inclined surface formed around the observation window and arranged at a position that faces the fluid jetting nozzle,
• wherein the distal end portion is formed with a second flat surface arranged on a distal end side of the first flat surface and parallel to the first flat surface,
• wherein the inclined surface is a surface that connects the first flat surface and the second flat surface together,
• wherein the first illumination window is arranged at the second flat surface and the second illumination window is arranged at the first flat surface,
• wherein the surface of the observation window is disposed so as to protrude by a predetermined distance from the second flat surface,
• wherein a top of the fluid jetting nozzle in the axial direction is disposed at the topmost side in the axial direction, and
• wherein the jetting nozzle includes a jetting port from which the fluid is jetted and a part of the jetting port is disposed on the distal end side with respect to the surface of the observation window in the axial direction.
