A scanning endoscope includes: an optical fiber that guides illuminating light and emits the illuminating light from a distal end an actuator for swinging a distal end of the optical fiber a first tubular member that encloses a distal end of the optical fiber and the actuator a holding portion that holds the optical fiber so that a distal end of the optical fiber is swung by the actuator a second tubular member that encloses the first tubular member a fixing portion that is disposed in an area perpendicular to a longitudinal direction of the optical fiber, the area being aligned with a position where the holding portion is disposed, and fixes the first tubular member to the second tubular member and a distal end fixing portion that is provided at a distal end of the first tubular member.
