A scanning endoscope comprising a light transmitter, an actuator, and a force transmitter, is provided. The light transmitter emits a beam of the light exiting the first emission end. The light transmitter is flexible. A longitudinal direction of the light transmitter is a first direction. The actuator is mounted near the first emission end. The actuator bends the light transmitter in a second direction by pushing a side of the light transmitter in the second direction. The second direction is perpendicular to the first direction. A force transmitter is oriented lengthwise in the first direction. The force transmitter is elastic. The force transmitter is positioned between the light transmitter and the actuator. The force transmitter exerts a pushing force supplied by the actuator on the side of the light transmitter while the force transmitter is deformed elastically toward the first direction.
