1. An endoscope configured to be connected to a light source assembly emitting an illumination light in which a plurality of color lights are mixed by a plurality of light emitting diodes (LEDs) emitting color lights different from each other, the endoscope comprising:
an insertion section that is to be inserted into an object to be examined;
an operation unit that is connected to the insertion section;
an illumination light-emission end that is provided at a distal end portion of the insertion section;
a light guide part that guides illumination light and that includes a plurality of light guides guiding the illumination light emitted from the plurality of LEDs to the illumination light-emission end, and an optical lens suppressing a variation in a relative intensity of each color light of the illumination light, which is guided by the plurality of light guides and is emitted from the illumination light-emission end, with respect to a light distribution angle; and
an optical connector that optically connects the planarity of light guides by holding the plurality of light guides and the optical lens,
wherein the optical lens is disposed between the plurality of light guides, and
the optical connector and the optical lens are provided in the operation unit,
wherein the insertion section includes a protection sheath and a shaft member inserted into the protection sheath,
the operation unit includes an operation unit body connected to a proximal end side of the shaft member,
the optical connector is fixed to the protection sheath, and
portions of the plurality of light guides held by the optical connector are rotationally moved in a direction around an axis of the insertion section together with the protection sheath.
