An endoscope, at least a part of which is introduced into an object to be observed to image an internal subjects includes; an illuminating device which illuminates the front side and is disposed so that a normal line M is perpendicular to an introduction direction (X direction); and an imaging unit which images the front side and is disposed parallel to the illuminating device. The illuminating device includes an organic light emitting layer which is interposed between two electrodes, a light shielding portion which blocks first light proceeding in a direction of the normal line among the light generated from the organic light emitting layer, and a light extracting portion which is provided at the tip end of the organic light emitting layer and extracts second light proceeding in an in-plane direction of the organic light emitting layer from the tip end among the generated light to emit the second light to the front side.
