Scanning endoscope with longitudinal vibration absorption

A scanning endoscope, comprising:

• 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 in response to a provided voltage to scan with the light emitted from the distal end of the optical fiber;
• a ferrule that is interposed between the optical fiber and the actuator, and transmits, to the optical fiber, force corresponding to the expansion and contraction of the actuator;
• a ferrule holding part that is connected to the ferrule to hold the ferrule;
• a lens holding part that has a space containing the optical fiber, 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 emitting illuminating light to an object;
• and
• an absorption part that is provided between the ferrule holding part and the lens holding part, and absorbs vibration, in a longitudinal direction of the cylindrical member, of at least one of the ferrule holding part and the lens holding part.
