Provided is an endoscope that can suppress breakage of an optical fiber and has excellent assemblibility and handlability. An endoscope includes a light guide that guides illumination light created by a light source device from the light source device via an operating part of the endoscope to a distal end part of an insertion part of the endoscope through an interior of an endoscope. The light guide includes a first optical fiber bundle; a first protective tube that covers the first optical fiber bundle from the distal end part to the operating part; and a second protective tube that is connected to a proximal end part of the first protective tube and covers the first optical fiber bundle. The first protective tube is made of a non-porous (solid) fluororesin. The second protective tube has a bending stiffness smaller than the first protective tube.
