An endoscope includes: an insertion portion including a distal end portion, to be inserted into a subject observation means disposed in the insertion portion an optical member configuring a part of an outer surface of the distal end portion, through which a photographing light to be incident into the observation means transmits a first hydrophilic portion that is film-formed at least on a surface of the optical member a second hydrophilic portion that is film-formed on a first surface of the distal end portion in which the optical member is disposed and a third hydrophilic portion that is film-formed on a second surface separate from the first surface of the distal end portion. The endoscope can thus clearly photograph an image of the inside of the highly humid body cavity even if an operation is performed for a long time period with the endoscope left inserted in the body cavity.
