Abstract:
1. An endoscope comprising: an insert unit that includes an end hard portion; a camera module formed in the end hard portion; a photographic lens unit that includes a photographic lens and a housing holding the photographic lens; a prism that includes an incident surface to which photographing light from the photographic lens is incident, a reflecting surface at which the photographing light incident to the incident surface is reflected, and an emitting surface that emits the photographing light reflected at the reflecting surface; a prism holding frame that includes a mounting tube portion mounted on one end of the housing, an opening through which incident light of the incident surface of the prism passes, and a prism fixing surface to which a peripheral edge of the incident surface of the prism is fixed; an image area sensor that is mounted on the emitting surface of the prism; a circuit substrate that drives the image area sensor; a transmission cable that includes wires connected to the circuit substrate and an outer cover that bundles and protects the wires; and a cable connecting fitting which is close to the image area sensor and disposed so as to be parallel to the image area sensor, and comprising: wherein a width of the connection plate unit in a direction orthogonal to the optical axis of the cable connecting fitting is less than a width of the connection plate unit in the direction perpendicular to the optical axis of the image area sensor, and the connection plate unit is disposed in a vicinity of a cylinder of the end hard portion.
