An endoscope includes an insertion part, an end surface provided on a distal end of the insertion part, a plurality of illuminating lenses disposed on the end surface, a forceps port disposed on the end surface, an imaging sensor configured to capture an image of a subject, an imaging lens disposed on the end surface on a same optical path as the imaging sensor, and a measurement auxiliary light head from which measurement auxiliary light is radiated within an imaging range of the image captured by the imaging sensor, the measurement auxiliary light head being disposed on the end surface. When the end surface is viewed from a front, the plurality of illuminating lenses are disposed on two sides of an optical axis of the measurement auxiliary light and are disposed on two sides of a line connecting the forceps port and the imaging lens.
