Endoscope

An endoscope comprising:

• a distal end rigid portion provided at a distal end of an insertion section, and including a through hole penetrating from inside to outside;
• an elongated image pickup section provided inside the insertion section, a distal end of the image pickup section being fixed in a state of being inserted in the through hole;
• a light guide fiber bundle provided inside the insertion section, and including distal end molded portions each having a distal end molded to have an outer shape that is specified in advance in relation to another component inside the insertion section, the distal end molded portions being inserted and fixed in the through hole, the light guide fiber bundle being formed as one bundle from a proximal end portion to a predetermined branched portion on a distal end side, and formed by being branched into a plurality of bundles on a distal end side with respect to the predetermined branched portion;
• a plurality of first cover tubes made of expanded polytetrafluoroethylene, and respectively covering the plurality of bundles from the distal end molded portions to the predetermined branched portion;
• and
• one second cover tube of a material other than the expanded polytetrafluoroethylene, covering the one bundle from the predetermined branched portion to the proximal end portion,
• wherein the plurality of bundles of the light guide fiber bundle formed on the distal end side with respect to the predetermined branched portion are disposed while being compressed by the image pickup section through the first cover tubes in such a way that minor axes are 90% or less of a diameter of a case where each bundle of the plurality of bundles is formed to have a circular cross section.
