Abstract: A scanning endoscope includes: an optical fiber that guides light emitted from a light source section, and emits the light from a distal end; an actuator that expands and contracts to scan with the light emitted from the distal end of the optical fiber; a ferrule that transmits, to the optical fiber, force corresponding to the expansion and contraction of the actuator; a ferrule holding part that holds the ferrule; a lens holding part that is formed of a cylindrical member provided outside the optical fiber along the optical fiber, and holds a lens, the lens receiving the light emitted from the distal end of the optical fiber; and an absorption part that absorbs vibration, in a longitudinal direction of the cylindrical member, of at least one of the ferrule holding part and the lens holding part.
