Abstract: Provided is a scanning endoscope including: an insertion portion that has a distal-end section and a proximal-end section; a light-guide optical system that guides illumination light toward the distal-end section; a spherical lens that is disposed in the distal-end section and that radiates the illumination light guided by the light-guide optical system onto a subject; an optical waveguide that extends from the distal-end section to the proximal-end section, that receives observation light coming from the subject, and that guides the observation light; and a light detector that detects the observation light guided by the optical waveguide, wherein the optical waveguide is inclined, at the distal-end section, in such a direction as to approach an optical axis of the spherical lens toward a distal end.

Abstract: A scanning endoscope includes: an optical fiber for illumination including an incidence side to which illumination light enters and an irradiate side from which the illumination light is irradiated, and configured to irradiate an object from the irradiation side with the illumination light; a holder configured to hold the optical fiber; a plurality of drive elements arranged so as to make the optical fiber swing between the irradiation side and the holder, and configured to make the optical fiber swing according to a drive signal; and a cylinder made of metal, and securing the optical fiber and the plurality of drive elements, wherein the cylinder is electrically connected to a ground potential.
