An objective of the present invention is to carry out a desired illumination over an entire range from a close-range view to a long-range view, and to carry out a clear observation even over any observation from the close-range view to the long-range view. Provided is an endoscope device, comprising an observation optical assembly (3) which is disposed in an insertion part of a leading end of the endoscope device and is for observing an object to be observed, and a plurality of illumination optical assemblies (2a, 2b) which are disposed in the insertion part (1), distribute illumination light which is emitted from a light source to the object to be observed and illuminate the same field of vision. At least one of the plurality of the illumination optical assemblies is a first illumination optical assembly (2a) having a convex lens, and at least the other of the plurality of the illumination optical assemblies is a second illumination optical assembly (2b) having a concave lens. |
