Abstract
There are provided an endoscope in which adhesion strength between two optical members can be enhanced and an endoscope apparatus including the endoscope. An endoscope includes an insertion part that is to be inserted into a subject, a first unit that is built in a distal end portion of the insertion part and includes a prism, a second unit that is built in the distal end portion and includes a cover glass, an adhesive layer that is formed between the light-emitting surface of the prism and the surface of the cover glass and adheres the prism to the cover glass, and a resin layer that fills a gap larger than the thickness of the adhesive layer formed between the first unit and the second unit. The thermal expansion coefficient of the resin layer is set to 1/10 or less of the thermal expansion coefficient of the adhesive layer.
